Exactly. It was pilot error, and I would venture to say it was the error of the fighter plane not estimating the speed of the B-17 correctly. From most of the videos that I've seen, on here and in other places, the pilot of the fighter plane appeared to be trying to turn behind it, possibly demonstrating a strafing run on the B-17 and was going too fast, which is why he clipped off the back end of the B-17.
And, for you people who say these planes should have been grounded, or who are thinking that there were passengers on it, you should really read/watch a news report about this. It was an airshow demonstration (passengers are NOT allowed on demonstration flights), and the B-17 was crewed normally (5 people onboard) and the fighter plane had only the pilot in it. And, the aircraft that show up in an airshow are VERY well taken care of, and the maintenance on them is up to date and done well. If it weren't, they wouldn't be allowed to fly in the show.
Yeah. This was a tragedy. Lives were lost and historical artifacts were destroyed. But, we should look more to the people that died in this accident rather than worry about the planes that were lost.
And..................I hate to say it..................but pilot error happens. I remember that our sister squadron (VFA-136) lost a pilot and an FA-18 during a detachment to Fallon. Seems he had his head in the cockpit and missed the mountain coming up in front of him and flew into the ground. It happens. Not very often, but it does happen. Just like you can get distracted looking at things inside your car and end up going off the road, the same thing can happen to a pilot in an aircraft. Only trouble is, instead of doing 30 to 60 mph like a car does, the plane is doing 100 plus in the air, with very little time to react and correct if something bad is gonna happen.
I feel for the people who died and all of their families.
