I saw multiple footages from many feeds. Looked almost like the Kingcobra pilot was
a) unconscious at the controls or
b) with jammed controls or
c) maybe passed out because of maneuvers or
d) even intentionally targeting the B-17 (who knows why).
He headed straight for the midsection of the B-17, splitting the fuselage and wing sections of the larger B-17 in half so the wing separated from the two front and aft fuselage pieces which floated down and burst into flames.
Hitting the B-17 with such force/speed that the Kingcobra itself disintegrated into a thousand pieces on impact.
Just horrific to watch.
RIP to the unfortunate pilots and airmen souls who perished and condolences to their families.
These were older retired folks just interested in flying historic aircraft as a hobby.
