F/A-18 Hornet fighter jet
In February 2004, a twin-engine supersonic, all-weather carrier-capable multi-role combat fighter jet was auctioned on eBay. I didn’t even know that was legal, but, frankly, I find it sort of awesome. The owner of the plane purchased it from a scrap yard and he had offered to have the plane restored for a “Buy It Now price” of $9,000,000. However, sadly, the auction ended without a winning bidder.
