Sealand AFB (Shotwick AFB)

Following a bombing exercise off the RAF Penrhos, Wales, a formation of 14 Avro Anson was returning to its base at RAF Bircham Newton with an intermediate stop at RAF Sealand. En route, while flying southwest of Llandudno, the leader went through a foggy area and instructed all other crews to gain altitude. While on the left of the formation, the Anson was flying at a height of some 100 feet when its pilot decided to gain altitude. The twin engine aircraft went out of control and crashed into the sea of Penmaenmawr. All three crew members from the 220th Squadron were killed.
Crew:
Sgt William Henry Victor Rimer, †

The crew was performing a ferry flight to RAF Sealand. The airplane overshot runway and hit a fence at the end of the terrain before crashing in a muddy field. Both crew members were injured and the aircraft was destroyed.

The pilot was completing a local solo training sortie at RAF Sealand. On approach, in circumstances that remains unclear, the aircraft collided with another RAF Avro 504N registered J8533 with two pilots on board. Following the collision, both aircraft dove into the ground and crashed near the airfield. One crew on board J8533 survived while both other crew members were killed.
Crew involved:
F/Lt Murray Meyrick Restell-Little, †
P/O John Frederick Napier Fairbanks, †
P/O Patrick Hunter Dunn.
