Ooh, that video is just sickening. To think that bomber survived WW II and all the thousands of hours in demo flights to go down with the volunteer crew. The only good thing is they only had a couple seconds to contemplate their fate.
The pilot of the small plane was unbelievably incompetent. On a clear day, no less.
It’s probably the famous Commemorative Air Force B-17 “Sentimental Journey”. Horrible situation all around.
