YA-10B Night/Adverse Weather two-seat experimental prototype, the sole dual seat A-10. The aircraft was converted from an A-10A. The unique aircraft, once built as YA-10A, made its first flight from Edwards on 4 May 1979. After several tests, the US Congress did not approve funding for the project, so the whole was cancelled. The aircaft is now preserved at Edwards. It is seen here after its period of storage and was prepared for preservation.

A very unique Warthog, the YA-10B. This is the only two-seat version of the A-10 ever built. The YA-10B is now kept at the Air Force Flight Test Museum at Edwards AFB.

This is the first ever built A-10 and is also the only two seater A-10 ever built. Owned by the Air Force Flight Test Center Museum it was displayed in a hangar, which was kept very clean!
