The Lockheed P3V-1 Orion makes its first flight at Burbank, Calif. A development of the turboprop-powered Electra airliner, the Orion is the Navy’s new land-based patrol aircraft. In November 1962, VP-8, the first operational P-3 unit (as it was redesignated in 1962) goes into action during the Cuban Missile Crisis. The P-3 was still in frontline service in the US and in 13 other countries at the beginning of the 21st century.
