Core77

Video of the very strange McDonnell XF-85 Goblin, a "parasite fighter jet" tested out by the US military in 1948. Designed to be carried insider a bomber and deployed mid-flight through the bomb bay, the Goblin had folding wings. It also had no landing gear--it was meant to re-enter the bomber by means of, we're not kidding, a little hook that caught on to a retractable scaffolding-type device.

As rare as this plane is, we're pretty sure we've seen it before, via Wile E. Coyote and ACME.
