19370507: The first flight by a fully pressurized airplane, the Lockheed XC-35, occurred. The Army used the plane, a modified Electra, to test equipment and material for use in high altitude operations. A few aircraft prior to the XC-35 had been fitted with experimental pressure cabins, but none of the earlier models flew successfully.
19640507: A passenger shot the captain and first officer of a Pacific Air Lines Fokker F-27 en route from Reno, Nev., to San Francisco, Calif. The aircraft crashed near San Ramon, Calif., killing all 44 occupants. (See August 6, 1964.)
19750507: FAA and PATCO reached agreement on a two-year contract (signed and effective July 8). The contract’s 74 articles included a guarantee of controller inclusion in the Aviation Safety Reporting Program
