REASON FOR LOSS:
Taking of at 13:17 hrs on a daylight operation to Engelsdorf and Mockau railway yards. Hit by predicted flak just short of the AP. A fire was seen to break out in the starboard inner engine, though the flames were soon quelled. Height was lost, followed by a small explosion which turned the Lancaster onto its back. Diving steeply, the bomber hit the ground and exploded.
