The US military had a clever idea back in the 1950s: let’s build missile launch sites under the ice in Greenland. That project was called “Project Iceworm” and was secret: as a cover story, and to test the feasibility of this idea, Camp Century was built.
You can imagine this was a massive logistical operation. Especially when you consider that everything had to be hauled across the ice from Thule AFB, 150 miles away.
Spoiler: it turns out that the ice sheet shifts. A lot. Which makes missile bases under the ice really not feasible.
Bonus: from the same source, the Charlie Dean Archives, “Faces of Rescue”, documenting a typical rescue mission for an Air Force pilot shot down over Vietnam.
I enthusiastically recommend “The Man Who Would Be King”. I have not seen “Star Trek VI”, but I know some other readers of this blog have and may be able to comment upon that film.
Noted: THR claims he was a die-hard “Star Trek” fan, even before doing “Star Trek VI”. The THR story includes a clip from “The Captains” with Mr. Plummer and William Shatner talking.
