I presume he's complaining about the movie version. Of course, they don't refer to the jet by name onscreen. Nearly 40 years of comics reading, and I never realized that they were called quinjets because they had 5 jets....
^ I'd always assumed that there were five of those aircraft available and that the name derived from that.
I was under the impression that it was the "quintessential jet" designed so anyone could fly it, including The Avengers, most of whom were not trained pilots.
Doesn't "quin" actually refer to one of the children born as quintuplets? Kind of how someone is a twin despite being just one person.
If you're thinking of babies, "tuplet" can be added to a couple prefixes, like quintuplet and octtuplet... oct s a bad example. Hextuplet... "Sextuplets" is 6. Probably something to do with an aversion to witchcraft.
It's because the design (at least initially) called for five engines: http://scifi.stackexchange.com/questions/16526/etymology-of-the-name-quinjet The diagram at the bottom labels 4 of the engines, and the big, unlabeled afterburner at the center makes 5.
Not sure who designed the "signature" version of the comics, although I know that it dates back to at least the late 1970's. The cutaway art is by Eliot R. Brown from the original edition of the Official Handbook of the Marvel Universe.
The original quinjet dated back to the John Buscema days, but that refined late 70s version probably originated with Perez or Byrne.
There are two main aft-mounted jets for forward thrust, two wing-mounted lift-fans with presumably their own two jet engines mounted internally in the lower pods alongside the cargo bay fuselage (similar to how the F-35's lift-fan is tied to the main jet engine) to provide greater vertical thrust for the large aircraft weight and payload, and possibly one additional jet engine mounted internally that serves as a reserve for all the others for emergency redundancy. Five jets. It's not explicitly pointed out, but four engines are visually supported, and a fifth is not hard to imagine given SHIELD's tendency toward redundancy. Especially given the modified C-17 "Bus" in Agents of SHIELD with its additional two redundant engines mounted aft:
Actually what set off my rant was Marvel's Avengers Assemble episode with Hyperion. But there are plenty of other examples. I'll see if I can manage a screenshot of the quinjet in that ep.
The Hyperion episode premiered a month or two ago, but the Squadron was not in it other than reference images. The story also took it's own spin on the source material, but it shared themes with the various depictions of the Squadron.
