What happened
During a routine local training exercise at RAF Sealand, an Avro 504N with registration J8533 was on approach. The specific circumstances leading to the incident remain unclear, but the aircraft collided in mid-air with another RAF Avro 504N, registered J8676. Following the impact, both aircraft lost control and dove into the ground near the airfield perimeter.
The crash resulted in significant casualties. One crew member aboard J8533 survived the accident, while the other two individuals on board were killed. The source material identifies the deceased as officers serving with the unit, though private names are omitted in this record to maintain neutrality and focus on the operational facts.
