You have to love that there is a little Aussie-built machinery in use at Beale Airforce Base to help land U2's... the humble Monaro.
Pontiac GTO's (rebadged Holdens in our language) are used to chase U2's down the runway as they land, issuing trim instructions to the pilot so that he doesn't smash a wing tip into the ground which might see it perform a ground loop.
