The 21st Century people escape 10,000 BC in a F-117, then the program goes to a commercial break. When the commercials end and the program returns, the F-117 is in the middle of a field. As fast and heavy as the f-117 is, there is no possibility of it landing in a field without crashing and killing everyone on it. It would have had to land on a hard tarmac and a field is NO hard tarmac. Ergo, just another really bad gimmick in a really bad program.
