I think this topic is getting away from warbird information but, I would like to add my conjecture about the Lindbergh kidnapping before Scott moves this discussion to the Off-Topic section.

I think the kidnapper intentionally killed the child while he was asleep in the crib. Why? Ever wake up a sound- to -sleep child? I think the kidnapper understood the difficulty of abducting a small child, hold him with one arm and climb down a ladder from a second story window...
.without making any noise. Also, can you imagine trying to care and feed a small child without be heard or noticed for
several days . I think the skull damage was from a hammer blow while the child was in the crib, the body desposed of quickly and I think that was the original plan.
By the way, I tried to post my conjecture on the CAL website but, was denied admission.
