ukanon with a weird linkage. With the various references to 40,000 foot view, I had to do a double take whilst doing a read on a classic of tv entertainment, Captain Scarlet and The Mysterons.

The good guys, Spectrum used Cloudbase, an airbourne aircraft carrier at 40,000 feet to conduct operations… Reflecting on that, and on the Helicarrier from the Marvel universe, it makes you wonder if there is actually something up there…
