Yeah, always forget about hanger 23. Probably because I was a such a fan of the 1980 film Hanger 18. OMG, i enjoyed that as a kid, but it also scared me, because at the end, they say the aliens are coming back... Before the hanger gets blown up and all that's left is the UFO...

Ummm, I wonder if Douglas Adams 42 is referenced to a hanger, perhaps where the Ark of the Covenant is stored.? LOL

Thank you, Sir!
