Today's subject, one of the odder little planes, the
XF-85 Goblin:

A bit of background first. In the 1950s, the primary long range bomber of the Strategic Air Command was the
Convair B-36:

It was a big aircraft...

(Too big to fit in the frame all at once...)

(Even this couldn't get the entire plane in the shot!)
...one of the biggest ever built, and the only piston-engined plane that was bigger was the Spruce Goose.
Yes,
piston-engined.

(Of course, they had to fit jets in there too...)
The B-36 was this weird piston-engined hybrid relic as jets were taking over the aviation world. Unfortunately for SAC, the B-36 was the only plane big enough to carry the early hydrogen bombs - so until the B-52 finally replaced it at the end of the decade, SAC flew this piston-engined giant.
Piston engines are
slow... slow enough that there were genuine worries about the B-36 getting shot down. But the distances it flew were too long for jet fighters to escort it all the way.
So someone had the bright idea... hey, it's got this big bomb bay, why not stick a mini-fighter in there?
Enter the Goblin.

Take a little tiny airplane, give it a trapeze hook to lift it in and out of the bomb bay, and the B-36 could carry its own escort with it.

Unfortunately, while it was apparently a pleasant little aircraft to fly, its performance couldn't match up to contemporary Soviet jet fighters. Worse, it was so small and light that the turbulence from the big B-36 knocked it around when it tried to hook up to the trapeze; the test pilot only managed it three times out of all the test flights. So the little fighter was canceled; sadly, if understandably.
