I bought an F-18 Hornet a few years ago. When it finaly arrived in the mail I found out that it didn't work! I had to spring for the return postage!
Ever since then I stopped buying military hardware on eBay.
It arrived in the dead of winter so I decided to use frozen over Lake Michigan for a takeoff runway. Unfortunately it broke thru the ice and sank on me, and since it is completely stealthy, I cant locate it..., sigh.
