✦ Synopsis

CURRENT Tot'~CS IJ. F. I, pact of a bird into a heavy dualrailed sled during an 850-mph. run tore loose ½-inch sheeting at the bolted seams.

Additional incidents of this kind included a four-inch rupture in the wedge-like steel prow of a sled speeding at 2850 mph. A 375-1b. sled was also twisted while traveling at 1500 mph.

According to Lt. Col. Donald H. Vlcek, Chief, AFMDC's Test Track Division and the man mainly responsible for the track and its supermodern equipment, "high velocity impact" causes this particular phenomenon in the same way that lighter materials may be driven through solid tree trunks by a hurricane's force, or grain-sized meteorites moving through space at near-ultimate velocities could tear apart the solid steel of a missile or a space craft.

Meanwhile, Holloman's sleds are still moving, though, as Colonel Vlcek remarked: "We'd have one less technical headache if somebody came up with the perfect answer about what to do with the birds." In the meantime, the technicians at Holloman are trying to aware the birds from their railperching pastime with all the weird sounds they can find.
