Reddit user claiming that it was a P-63 Kingcobra in the collision with the Flying Fortress

That fits. It wasn't a P-51.

DALLAS (AP) — Two planes have collided and crashed at an air show in Dallas, Texas, the Federal Aviation Administration said Saturday.

Emergency crews were responding to the scene at the Commemorative Air Force Wings Over Dallas show at the Dallas Executive Airport.

The Federal Aviation Administration says a Boeing B-17 Flying Fortress and a Bell P-63 Kingcobra collided and crashed around 1:20 p.m. Saturday. Officials said it was unclear how many people were on board both aircraft.

Several videos posted on Twitter showed two aircraft appearing to collide in the air before they both rapidly descended, causing a large fire and plumes of black smoke to billow into the sky.

The FAA and the National Transportation Safety Board were launching investigations.

I doubt it was deliberate, but it certainly reminds me of gross negligence like when bikers zoom and weave between slow freeway traffic.

That asshole had the entire sky to work with and he decides to go right where a b17 is.

B-17 doesn't have ejection seats.

Looks like they had two P-63s:

Inside job

That's terrible.

Oh man, absolutely terrible

Nice catchup tackle

It was an airshow. It was almost certainly the Commemorative Air Force flying those airplanes. They used to be known as the Confederate Air Force. It was probably during the part of the show where they do their Pearl Harbor portion. (B-17s arrived at Hickam Field in the middle of the attack. They were low on fuel and had to attempt to land.)

Those demonstrations are heavily choreographed and the collision was almost certainly inadvertent. There is no way the pilot of either aircraft would do something like that intentionally. It was almost certainly the fault of the pilot of the smaller aircraft. We'll probably never know exactly why it happened.

There as so few of these old warbirds left and now a B17 was senselessly lost along with the pilots. Pretty soon there will be no flying of these magnificent planes due to carelessness..
Prayers to the pilots families…

Absolutely awful.

Whoever is driving that bi-plane in the bottom right gets a free pass if they pooped their pants.
