- NATION, Page 25American NotesAIR SAFETYA New Use for Old Bombers
-
-
- Authorities in Tucson recently learned that explosives will
- be detonated in more than two-dozen aircraft beginning this week,
- but they are not trying to stop the bombings. In this case the
- Federal Aviation Administration will have a hand in the
- blasting.
-
- Thanks to last year's disarmament agreements with the
- former Soviet Union, 30 B-52 bombers are among the weapons that
- will be destroyed at Davis-Monthan Air Force Base. The
- demolition provides the FAA with a chance to learn how to design
- passenger airliners that are more resistant to terrorist
- explosives. "The B-52s are a real windfall," says Lyle Malotky,
- the FAA's scientific adviser for aviation security. "When we
- laid out this program two years ago, we didn't expect to have
- such resources."
-
- Sorting through the debris of terrorist bombings like that
- of Pan Am Flight 103, which killed 259 passengers,
- investigators found that while the blast blew a hole in the
- plane's fuselage, the breakup of the aircraft was caused by
- cracks that allowed the craft's skin to peel away. The
- theoretical answer: use materials that prevent cracks from
- forming, and the plane's structural integrity will be maintained
- to allow for a safe landing. The B-52 bombings will help
- determine how much force will punch a hole in an airliner's
- skin.
