Crash investigation

First published on August 2, 2013, this is a site that I have not yet been able to return to. I won’t get into the details as to why, but some reasons have been due to health. I do have a few more documents than when this was first published, so I do plan to update the information a little and share a better analysis. I do still hope to return to the site, or if nothing else, visit the memorial at the top of Crash Hill. There are still many people in Newfoundland who remember this incident, and some who were directly involved who have stories to share. I do not have notes or recordings of these stories, but I hope they do get shared publicly as it is another important part of our aviation history.

On 3 October 1946, an American Overseas Airlines (AOA) NC90904, a DC-4, took off from Harmon Airfield in Stephenville, NL at 0833 GMT. Moments later it crashed in to Hare Hill, killing all 8 crew and 31 civilians (Wilkins 1946). This was “the worst disaster in the history of American commercial aviation” (Canadian Press 1946) with a larger death toll than the Sabena disaster which took place in Gander, NL, two week previous. The aircraft had departed from LaGuardia, New York, destined for Berlin, Germany, with stops scheduled in Gander, NL, and Shannon, Ireland (Author Unknown 1946b). The AOA aircraft had been diverted to Stephenville due to thick fog around Gander (Canadian Press 1946). The passengers consisted of 12 women and 6 children en route to be reunited with family stationed in Europe as well as businessmen bound to assist in the rebuilding of Berlin (Wilkins 1946).

The DC-4 was scheduled to leave from runway 30, but a sudden wind change diverted the aircraft to runway 7. The aircraft impacted the side of Hare Hill about 2 and a half minutes after take-off (Wilkins 1946). The subsequent explosion could be seen from the airport (Landis et al. 1947). At first light, the site was checked for survivors by passing aircraft, but none could be found (Author Unknown 1946a). A recovery mission departed at first light that morning to investigate the incident and cover the wreckage. Initially, the plan was to blast above the site to cover the wreckage and human remains, but when the size of the site was established, it was decided to create a mass grave near the wreck site for the human remains (pers. comm. Leo Fitzgerald 2013). Over the next couple of days, bodies and personal effects were recovered, and where possible, identified. The rocks above the site were then dynamited to cover the aircraft, but the site was too large to be completely obscured (Fagan & Fitzpatrick 1946). Personal reports from Nelson Sherren (2011) indicate that the hill may have been blasted again in the 1970s in an attempt to cover more of the aircraft. In 1946, only days after the crash, a memorial cemetery was built at the summit and a large monument which lists the names of the victims was air lifted to the memorial cemetery. Family members were invited to view the site and drop wreathes from an aircraft passing overhead. A Catholic, Protestant and Jewish burial service was held on the helicopter for those who had perished (Time 1946). In 1989, the memorial cemetery was redone when Dixie Knauss, a surviving family member, visited the cemetery and found that all of the crosses had fallen. She attempted to secure acrylic crosses, such as are used in United States military cemeteries, but could not and the site was redone with wooden crosses (Knauss 1989).

Over time the site was lost. The hill was now known as Crash Hill, and it was common knowledge in Stephenville that a plane crash had taken place, but the location and specifics about the crash were less known. In fact, hunters and hikers had been exploring the area trying to find the site, but could not (pers. comm. Don Cormier 2012). It was believed that when the site was dynamited it had been successfully obscured and researchers were unsure that anything would remain.

In 2012, a small group of researchers, lead by guide Don Cormier, and based on a picture found in Our Lady of Mercy Church on the Port-au-Port in comparison to GoogleEarth images, located the site. Unlike what was expected, most of the wreckage remains. Much is obscured by blasted rock, which also makes the site extremely treacherous, but the aircraft remains. Archaeologists did a preliminary survey of the site, taking GPS readings and photographing pieces, but it was obvious that the site was too large to fully survey in the little time the team had on site. On a second trip that year, videographer Dave Hebbard and Cormier returned to the site and found further wreckage that was not photographed nor mapped on the first trip.

Next week, a slightly larger team will return to the site for a two to three day stay in an attempt to properly survey the site, find the extent of the site boundaries, and survey the memorial cemetery at the top of the hill. The site is difficult to access as Crash Hill is a fairly isolated site and the incline of the hill seems to be around 60 or 70 degrees. That coupled with the loose rock leftover from blasting makes it a difficult site to navigate and impossible to bring out much in the way of archaeological equipment. Researchers will be limited to a handheld GPS and measuring tapes and a compass to survey the site.

Once this survey is complete, the data will be mapped to give a better idea of site distribution. As well, when the top of the hill is mapped, it will show the extent of the damage that time and the elements has done to the memorial cemetery, which will hopefully end in the site being redone, perhaps with the plastic military crosses that Dixie Knauss wanted in 1989 (Knass 1989).

*03 October 2013 update: Myself and my team did not make it out to the site this year, we were kept away due to poor weather. I hope to get out next spring or early summer to continue to work. The presentation at the Stephenville Regional Museum of Art and History was well attended, and I had the opportunity to meet many wonderful people from the area, many of whom were happy to share stories with me. I hope to have many more conversations with the people of the area, and do much more research that will be of interest to them.

*04 April 2016 update: Poor health has kept me away from the site. It is a difficult hike and while the research is important, I must put my own well-being first. I have gotten much stronger since my health scare in 2013-2014 have hope to soon be able to push myself into more strenuous hikes.

Royal Canadian Air Force Lodestar 557 (Borden DfAp-15) is currently located on the edge of a tree-lined bog with all of the wreckage being located in the bog. It sits between Radio Range Road and Boot Pond Road (map 1), but is a long and sometimes difficult hike through trees and bog. In fact, researchers had difficulty finding the sites, even with the information provided by historians, locals, and aviation engineers. The site is relatively intact, but is heavily contaminated. The point of impact where the aircraft burned is heavily contaminated with fuel, and much of the water around the wreckage has the rainbow colour that shows contamination (figure 1). Any archaeological work done on site was done with protective material, including heavy duty gloves, to ensure that contaminated water did not touch skin. The site should be approached with caution and care taken to avoid any fuel contamination.

Lodestar 557 departed Moncton. New Brunswick, at 2345 GMT on 7 May 1943 on a cargo transport flight to Gander. At 0313 GMT the following day, the aircraft contacted the Aerodrome Control Officer at Gander Station to request landing clearance. The aircraft was given landing clearance by P/O Thomas Howard Murray, aerodrome control officer, and was told to check their wheels down. The messages were acknowledged by 557. At this time the ceiling was practically unlimited. The aircraft was heard to pass over Gander airfield shortly thereafter, but the ceiling had unexpectedly fallen to 700 feet. This lowering of the ceiling possibly meant that ice may have formed on the aerials. It is unlikely that icing would have occurred on the wings or engines. This fly over was apparently done on instruments. The Lodestar contacted the Control Officer to indicate they had missed the field and were to try again. The aircraft then acknowledged being given the ceiling height and barometric pressure by the station.

At this point, the landing of the aircraft on the control tower side was taken over by the station manager of Trans Canada Airlines (TCA), Mr. Harry Beardsell. The aircraft was carrying cargo and under the operational control of TCA and therefore should be under TVA radio coverage. Instructions were passed to the aircraft by TCA as to the proper landing procedures for Gander, and these were acknowledged. The aircraft broke through the now 600 ft. ceiling, and was advised to circle and approach runway 27 (note, runway 27 is no longer in use at YQX; ourairports.com). At this point, TCA spoke directly to the pilot. According to Beardsell, he advised Svendsen to make one more attempt before proceeding to Sydney where the ceiling was at 1000 ft. and visibility was 3 miles. P/O Murray, who was listening to the communications between the control tower and Lodestar 557 denied that the aircraft was advised of a secondary landing location. According to the radio log, it was actually Lodestar 557 who suggested that it would try for one more landing and if not successful would return to Sydney and TCA seconded the decision. The aircraft approached, but seemed to be lined up with the wrong runway and was advised to circle again and attempt runway 27. P/O Murray believed that the boundary lights were confusing 557, causing it to line up with the wrong runway, so he switched off the lights and informed the aircraft through Beardsell. One the second attempt, the aircraft did not turn enough and was again told that it would probably not make it to the runway and to attempt again. The aircraft was told to make a right turn over the field near the airport, but it could be seen that the aircraft would not make the turn successfully. The pilot was advised to pull up two or three times by TCA, but at this point 557 was in a steep bank and went into a stall, losing altitude until it crashed. One witness saw the aircraft moments before the crash and stated it was flying very low at 200 ft. with engines functioning properly. The crash was indicated by a flash followed by a second, brighter flash, indicating it had crashed and was burning. Fire trucks and ambulances were dispatched to the scene. It crashed at 0340 GMT on 8 May 1943 approximately two miles east of the RCAF Station in Gander. All crew were killed and found in their proper seats in the aircraft (Table 1; Mulvihill 1943). The crew were buried at the Commonwealth War Graves in Gander.

According to the accident report:

AIRCRAFT:               Scattered over a small area but distributed over approximately 190 yard line. The starboard wing tip made first contact with a tree and then the port with the resultant that the starboard wing came off first, followed by the port. The fuselage continued on and finally both wheels struck the ground, at this point the aircraft must have bounced into the woods where it caught fire and was almost completely burned out except for portion just forward of the rear door to and including the empennage.

EMPENNAGE:          The empennage [tail assembly] was twisted completely around and was facing in the opposite to normal direction (figure 2).

WINGS:                      Starboard damaged but not seriously while the port was fairly well intact, but both were torn from centre section outboard of root fittings.

FLAPS:                       It was observed on examining the crash that the section of flaps remaining on the centre section was in the up position. It is improbable the flaps would have been retracted as a result of the crash.

INSTRUMENTS:       There were no instruments or controls present to indicate the attitude [sic] of the aircraft or the performance of the engines.

ENGINES:                  Port engine was seriously damaged while the starboard was completely burned out. The salvage from the two engines would be almost negligible (figure 3).

UNDERCARRIAGE: The undercarriage was severely twisted but it appears certain that it was locked “down” at the moment of impact, since one of the [botusting] cylinders was found in the retractor or “undercarriage locked down” position and it is considered impossible for the cylinder to be forced into this position by a crash. The other cylinder was partially extended but this could have been caused by the crash. In addition one of the drag struts was observed to be buckled as indicating it had experienced a severe compression load which it could not experience if the undercarriage had been retracted.

GENERAL:    Other than the above, all other parts of the aircraft were so badly damaged or burnt that they were of no value in disclosing further information (figure 4; Mulvihill 1943b).

The aircraft had been certified as airworthy and in serviceable condition; the pilot, WO2 Svendsen, was fully qualified to fly a Lodestar in all conditions, and had twice flown the same route to Gander on transportation flights. The cause of the crash was determined to be “pilot error, while attempting to get into position to make approach under low ceiling” (Mulvihill 1943). The aircraft slipped or stalled after changing from a left turn to a right turn in an attempt to realign with the runway. Because it was already in low altitude, the slip or stall caused it to strike the trees while trying to recover from the turn. The report recommends safety changes to the airbase. As Lodestar 557 had to make a final attempt because it had aligned with the wrong runway, the report determined that the runway lighting system of the RCAF station in Gander was confusing and should be studied and improved (Mulvihill 1943).

Based on a comparison of the archaeological investigation and the incident report, the site is mainly intact. Even a comparison of the sketch in the report, the site map, and recent pictures of the site show an almost identical layout of the crash site. It is known that this site has been visited (based on conversations with people from Gander), but very little seems to have been removed. Interestingly, most people who visited the site in the past, or who know of it, have the impression that the site has largely been recovered or looted by salvagers in the recent past. Contrary to this, the site shows very little disturbance, to the extent that the tail rudder appears to be in the same location as indicated by the 1943 map. In agreement with the crash report, the cockpit, including all instruments, was destroyed. What is present on the site is an area of slag with pieces of instruments and aircraft scattered throughout. This area was explored by archaeologists, but instead of trying to measure in every piece and burnt fragment, some of which could not be identified because they were too deep under contaminated water to be moved, it was decided that the points of measurement would be taken around the area and large, identifiable pieces, such as engines, would be measured separately. In fact, it was a similar method used to create the 1943 map (figure 5; figures 6 & 7).

Due to the fact that the crash report describes the scene in such great detail, and the site is still very much intact, the archaeological analysis does not add much information about the crash. One exception is that pieces of the aircraft were found up to and over 30m west of the main impact point. These pieces were measure into the map first by using a 30m measuring tape until pieces were too far, then they were measured directly from the stadia rod. Most of the site was measured into the map using a measuring tape and surveyor’s level (figure 8). The pieces the furthest from the wreckage indicated that the burnt area was not the first area of contact during the crash, but that Lodestar 557 clipped the trees and began taking damage prior to the final impact. This is mentioned in the report, but the artifact distribution better indicates how the aircraft came in while attempting to turn.

While it was stated that the archaeological investigation did not add much to the information available in the incident report, this site is of archaeological importance due to the fact that it is very much intact. It is a relatively well-known crash site around Gander, but because it is a fair distance from any road or path, it is difficult to access and is therefore mostly untouched by site visitors. As well, the fact that the crash report and the archaeological investigation line up so neatly is a way for archaeologists to check their methods and make improvements for the investigation of other sites as necessary. Very little post-war damage has occurred at this site, and now that it is listed as an archaeological site and given its remote location, it will continue to remain intact.
