I’ve not heard any mention of B17 losses during takeoff in any of the books I have read.

… I’d imagine that there were a fair few weather related crashes on take-off during the poor winter of 1944 – a 390th BG B-17 crashed on 27 December 1944 attempting to get airborne from Framlingham/Parham – came down alongside the main Parham-Framlingham road, the explosion damaged every house in the village. although there was no loss of life on the ground (visited the excellent Framlingham tower museum last week. This incident is also cited in Parker ” To win the winter sky “)
