Pieces of the Concorde fetched outrageous sums at an auction this week, with many of them going for more than 100 times the asking price. The nose cone, expected to go for around $11,000, sold for more than half a million dollars. A pilots seat valued at $1,100 went for $50,000. Citing financial losses, Air France and British Airways a few weeks ago stopped operating the Concorde fleetthe worlds only supersonic passenger jets. British Airways is donating much of the profits from the auction to a childrens charity.
