Boeing Harrier (N94422)

It's a favorite of mine, but does not appear to be a "trainer"

FA is odd like that. ICAO code for harrier is HAR, wether it a TA-8, sea harrier, etc. this is a sea harrier FA.2

Art Nalls owns a two seat variant as well. He just successfully cycled the gear and finished up all the hydraulics. Next up is fitting engine and runs. Hope to have first flight by next year.
So he'll be the only person in the world to own a FA.2 and TA-8B that'll be airworthy.
