Spaceheads around the Air Force have to be asking themselves one question: Who the hell snagged their sleeve in the satellite? OK, maybe it’s not that simple. But a Government Accountability Office report found that a small piece of cloth stuck in a fuel line might have caused the problems the Advanced Extremely High Frequency satellite has suffered. The satellite will reach its intended altitude nearly a year late. Launch and operational delays have cost the government $250 million, according to the report. That’s some expensive cloth.
