A google came up with the following:

Semms the B24 killed many more crew than the B17 in accidents.
Nealy did the same for for my Pop as well, as he ended up in the Irish sea when a constant speed unit ran away and the wing came off in a training accident after VE day. Seems that the high aspect rato wing of the B24 was not up to the job required.

Just been corrected by Dad, It was a Mk 8 Lib and the failure was the electronic control of the turbo supercharging system. Resulting in a complete engine failue and Dad thinks large parts of the engine entered the cockpit when it blew up.
