Here's one from the experimental category. This is the XB-70
Valkryie program. A multi-mach bomber project. A few
things of note here are the articulating main landing gear,
movable wing tips amd six engines. This particular plane
later crashed and sadly killed it's pilots. If you look
closely as the Valkryie is landing, you will see a B-58 Hustler
chase plane
. Also, if memory serves me correctly,
the plane flexed so buch during sustained mach flight that
the white paint peeled off. You can see the missing paint
in the final shots of the video.
