In the early hours of 8th July 1944, a normally quiet part of rural Northamptonshire was a hive of activity as the 17 twinned engine Wellington bombers rumbled down the runway of their Turweston airfield home. With the Allied D-Day invasion having taken place the previous month, these young trainees were conducting a night-time flying exercise as part of their readiness to enter frontline bombing service for the RAF.
With a bright full moon lighting up his fellow circling bombers in the night’s sky, the Wellington of Pilot Officer Searles and his six strong crew took to the air. As they climbed into the inky darkness a fireball erupted. Searle’s Wellington had collided with another, and the two bombers crashed to the ground in flames. Both crews were killed instantly. 13 young men had died before their war had even begun… Garth Barnard strives to find out what caused the mid-air collision by reviewing eye-witness accounts, official reports, computer simulations and his own theories.
