... B-52 Stratofortress

... nose profiles of the B-52 heavy Strategic bomber. The top illustration is probably around the time of it's introduction into service in 1955. The lower illustration should be around 1960 (you can just see the nose of a 'Houndog' standoff missile hung from the wing on the right). The aluminum skin is so thin, that yes indeed, it does wrinkle. 

Guess somewhere along the way they decided to make sure everybody knew this monster belonged to the USAF and not... Luxembourg?
