What, pray tell, are they going to >blow up? Are these devices explosive bolts or photon torpedoes? If it's supposed to explode, it's ordnance. The storage and handling requirements don't really discriminate between explosive bolts and 30 mm cannon shells, for example. In ejection seats, the explosive materials are usually called pyros (for pyrotechnical materials?), as in canopy pyro or seat pyro. Maybe it's ordnance if it's outside and pyro if it's inside. -- Mary Shafer shafer@elxsi.dfrf.nasa.gov ames!elxsi.dfrf.nasa.gov!shafer NASA Ames-Dryden Flight Research Facility, Edwards, CA Of course I don't speak for NASA
