The #3 engine has started!
If you look very closely, you can see a little bit of smoke highlighted by the
tail of the aircraft.
This was only the second B-24 flight I'd seen (the other one being
one of Witchcraft's flights). Compared to the large number
of B-17 flights I've seen, I was impressed by the lack of smoke when
Witchcraft started her engines (although there was a
small amount of smoke noticeable). Although I mostly had my eye in
the viewfinder, I did not remember seeing any smoke whatsoever when
Diamond Lil started her engines, so there must have been very
little smoke indeed.
