American Notes
AIR FORCE
A $90 Million Mistake
</hdr><body>
<p> Who would place a $90 million, high-powered radar station so
close to an airport that it has to be shut down every time a
plane lands? Someone, it turns out, who should know better: the
U.S. Air Force Space Command. The problem exists at Robins Air
Force Base in Georgia, where a giant early-warning radar
searches for missiles launched from submarines. But the
apparatus is only 1.5 miles from the approach end of a runway,
and Air Force electronic engineers fear that its emissions
could trigger electromagnetic explosive devices on many
military aircraft. Those devices are used mainly to discharge
fuel tanks or fire air-to-air weapons. To guard against
accidental explosions, the radar is manually shut down for up
to 90 seconds whenever a plane approaches the field.
</p>
<p> While the Air Force insists that electronic flight-control
circuits inside its aircraft are shielded against radar and
radio emissions, it closed the radar station completely during a
precision-flying exhibition in November by its Thunderbirds
aerobatic team. Several Army BlackHawk helicopters have crashed
when their pilots flew too close to radio antennas elsewhere and
lost control of their choppers. The Air Force has now compiled
a list of 300 powerful radio transmitters in the U.S. that its
pilots must avoid by a certain distance. The list is secret.
