Looking for a Vintage Superhero glider.

[TEXASFETT]

Hey guys for some time now I have been looking for a these superhero gliders but can't find nothing. Looks like a plane with a hook at the nose piece and shoot it from a rubber band. It came as Spiderman,Hulk,Capt America,Iron Man and others. I would see the gliders in the old comic ads when I was little kid but do they still exist. Any info would help.
