Most B52s have the wrinkled skin at the neck, especially those involved in combat ops in V'nam.
Its the 'no flare' landing that does them in....front and rear gear land at the same time, cockpit carries on down.
Trubshaw did bring 002 to Yeovilton....not sure it was a particularly hard landing and at the time I'd have siad he was pretty experienced on type.
It was also not destined to fly again, regardless of the landing.
There are also some wrinkles on 01 at Duxford....
