HELICOPTER BRIEFS
• If a helicopter engine stops, its rotor continues to spin, allowing the machine
to slowly land, generally without crashing to the ground.
• Unlike airplanes, helicopters can hover or stop, fly backwards or sideways.
• Helicopters are used for rescues in both peacetime and during wars.
The first life-saving helicopter mission was carried out in 1944 and involved
a sea rescue.
• U.S. police and emergency rescue helicopters transport about 15,000 patients
annually. The method of moving sick and injured people to the hospital saves
thousands of lives each year.
• Helicopters can be flown across oceans if in-flight refueling is employed.
• If you want to travel 300 to 400 miles, the helicopter is often the quickest
means of transportation.
