Well, I've always liked the look of the Aardvark.
As for all the bad comments here, I can't argue with someone who has worked with it, but it must be remembered that the F-111 was a pioneering aircraft so bugs could be expected. The first mass produced variable geometry aircraft and very advanced avionics for the time in which it was introduced to service.
Read far enough back in the Vark's history and it had significant teething problems in its development before it ever hit unit service. The Australians had to lease 27 F-4Es for three years due to problems and setbacks in the F-111C's development. The F-111K order was cancelled by the RAF due to problems (shame, I would have like to see what domestic technology the Brits would outfit her with, RR Olympus engines perhaps...)
A lot of the developmental problems were in conjunction with the new technologies being brought forth in the bird, a lot of those technologies were the first generation of whatever they were and so problems would certainly work their way to the surface.
As for variable geometry itself, from all I've read its one of those things thats easier said than done. The Russians had similar developmental problems with the MiG-23 and I understand that such problems also had a lot to do with the demise of the Mirage G.8.
Call it a pig if you will, it flew in the face of conventional aviation design thinking at the time of its inception and for that and it s being able to soldier on fo 20+ years inspite of being dogged by the ghosts of its early development bugs, it does deserve a bit of respect.
Awesome looking bird if nothing else!
