@Coldfusion, the Island, the ship was sunk in WWII IIRC, Romans called the Island Mona, the Celts Mananan (a celtic god), in the local lingo that's Ellan Vannin, or the Isle of Man in English. 90,000 alcoholics clinging to a rock

Usually I refer to it as Fraggle Rock, or just the Rock but was feeling kind when I updated my profile.
I've always wanted to ask, are the high mushroom clouds we've seen in other calender shots (for example the shot of the demolisher racing to the battle at the pyramids) the product of 'mech explosions or do base defence reactors/Dropships go boom with even more force than a 'mechs explosion?
