O.k., that's just too darn bittersweet. They have built this as a tribute to their 19 ear old older brother who was shot down and killed in it. Damn.
I'm always torn as to whether these planes should fly or not. It is priceless. It is theirs and they can do whatever they please, but it would be such a shame to see it crash but such a site to see fly. It would be too much if any of them died flying this aircraft.
I have worked on many aircraft (under the tutelage of a qualified A.I., A&P, technically I was apprenticing). I have helped restore vintage, and maintain modern aircraft. I have seen that almost anything can go wrong. A very complicated system.
Great story. What brave men who flew those missions. I hope the brothers have the best of luck in whatever they endeavor.
