Hi all,
Rearwhelsteer888 - Isn't the F-12 and the SR-71, twin and single seat versions of the same airplane?
The F-12 being the much better version in its hey-day!
Saw a heap of SR-71s and U-2s parked at Palmdale, California, (about 120 miles north of LA), where Lockheed assembled both the C-141 and the P-3C years ago during my days of post production test flying of the RAAFs new P-3Cs in mid '86.
I've read that book relating the designing, development, test flying and in-service life of both the F-12 and SR-71.
It's a really interesting read, a fantastic airplane!
Cheers
