Lisa Nowak thought another astronaut, Colleen Shipman, was having an affair with a third astronaut, William Oefelein, because Shipman was flying from Houston to Orlando where Oefelein lives. Nowak was in love with him herself, despite the fact that she's married. So Nowak drove non-stop from Houston to beat the flight, without even stopping to urinate. In Orlando, she tried to waylay Shipman in the Orlando Airport parking lot. I don't quite get what she was attempting to do there, as it involves a wig, a trench coat, an air cartridge BB gun and pepper spray. Just weird and bizarre.
You think that, although astronauts are not saints, that they would be a higher class of crazy. Apparently not.
