Photo of the F-111F 'Aardvark' cockpit windscreen by Bob Nelson at the Grand Forks Air Force Base (GFAFB) 'Friends And Neighbors Day' on May 27th 1989.
The F-111 'Aardvark' was an all-weather attack aircraft, capable of low-level penetration of enemy defenses to deliver ordnance on the target. The F-111 featured variable-geometry wings, an internal weapons bay and a cockpit with side-by-side seating. The cockpit was part of an escape crew capsule. The wing sweep varied between 16 degrees and 72.5 degrees (full forward to full sweep). The wing included leading edge slats and double slotted flaps over its full length. The last USAF F-111s were withdrawn from service in 1996, replaced by the F-15E 'Strike Eagle'.(Wikipedia)
