Just a tragedy and a disaster for the Collings Foundation. They rely on these flights to fund their efforts to keep these heritage aircraft alive. Their B-17 and the B-24 do a fall round down the East, hopping from airport to airport, offering short flights to give people a sense of the experience..
I've flown on that bird, The brief hop from Westchester Airport to Manhattan and back, it would be brutal in a crash because there are not really great safety features for such an event.
Afaik, it was one of the first flights of the day, so the aircraft may have had more fuel than usual on board, which would exacerbate any problems.
My condolences and RIP for the victims. I hope it does not also kill the Collings Foundation.
