Since we did wander off a bit, and then got into rich people's toys, I saw a bit of TV yesterday (~ about 6 month's normal quota); was on Nat. Geog. The show was called Tycoon Toys (or something similar) and was about very rich peoples' favorites hobby - owning & flying ex-military jets. Many of these cost $1M a year each to maintain/run. Most gulp fuel at alarming rates. Some require 75 hours of maintenance for each hour of flight. There's a rich bloke in S. Africa who collects them, and he's got 30 different ones, each in perfect condition. He flies each one. Was thrilling just to watch. He has one that was the "fastest" made - climb rate of 50k feet per minute, and they showed it doing that right after take-off - a vertical climb. Awesome.
