Training

In flight, the twin engine aircraft collided with a USAF North American P-51D Mustang registered 45-11680. A crew member was able to bail out before the Invader crashed in a field, killing all three other crew members. The fate of the P-51's crew remains unknown.

The crew was performing a training sortie at Whidbey Island NAS when an engine caught fire in flight. The pilot decided to return but was eventually forced to make an emergency landing in a field. The aircraft belly landed and came to rest in flames. There were no casualties but the aircraft was destroyed.

The crew was engaged in a local training flight in Shell-Mera Airport. During the takeoff roll with both engines at full power, the aircraft swung to the right. The pilot in command over corrected so the aircraft veered off runway to the left, hit an earth mount and a tree stump before crashing into a building. While all three crew members were unhurt, an employee in the building was killed.

The crew was completing a training mission in Lisbon. Shortly after takeoff from Lisbon-Portela de Sacavém Airport, while in initial climb, the instructor shut down an engine. The aircraft stalled and crashed near the runway end. While all five crew members were injured, the aircraft was destroyed.

During takeoff from Lough Erne off Enniskillen, the seaplane hit several waves in strong winds. The departure was interrupted and the aircraft came to rest. There were no casualties but the airplane was damaged beyond repair.

The twin engine aircraft crashed in unknown circumstances near the Çubuk dam, killing the pilot, sole on board.

The crew was completing a local training sortie in Madrid AFB. On final approach, the twin engine aircraft collided with a private Luscombe that just took off from the same runway. Both aircraft went out of control and crashed near the runway threshold. All four crew members on board the C-47 and the pilot of the Luscombe were killed.

The crew was engaged in a local training flight in Albacete. Shortly after takeoff, while in initial climb, the four engine aircraft collided with a small private plane. Both aircraft went out of control and crashed near the runway end. All four crew members on board the Halifax and the pilot of the private plane were killed.

The crew was completing a training sortie in Lübeck, towing a glider. While flying around the airport at low height, the left engine failed. The crew immediately dropped the glider and reduced his altitude in an attempt to make an emergency landing. The aircraft crash landed in a field located near the airport, slid for several yards and came to rest in flames. Both pilots escaped uninjured while the aircraft was partially destroyed by fire.

The crew was engaged in a local training flight on this brand new aircraft that was delivered to KLM last April 22. After several touch and goes completed without any issues, the instructor decided to perform a takeoff with the engine number one voluntarily inoperative. Ready for departure on runway 23, the crew increased power on all four engines and started the takeoff procedure. At a speed of 137 km/h, the captain started the rotation and the nose wheel left the ground. At a speed of 169 km/h, the instructor decided to reduce the power on the engine number one and pull the power lever to the back. At this moment, the aircraft was still on the ground and slightly deviated from the runway center line to the left. The captain tried to counteract this with the tail when the right main gear left the ground. Due to the presence of obstacles ahead, the instructor decided to increase power on the engine number one that oversped. The left wing dropped and hit a rocky wall, causing the aircraft to stall and crash into a ditch. All five crew members were injured while the aircraft was destroyed.
