Researchers at the Flight Path Learning Center and Museum at Los Angeles International Airport (LAX) said several recent donations have increased the number and variety of available reference materials.

Historic technical and marketing documents from several present and past domestic and international airlines were donated to the learning center’s William A. Schoneberger Research Library, according to Rowena Ake, Flight Path president.

Included are history and marketing materials from Mexicana Airlines, safety instructions for various aircraft of the American, Pan American, Southwest, Northwest, National, United, Japan, Capitol, Hughes Airwest, Republic and UTA airline fleets, and a collection of documents from the Flying Tiger Line, including route performance, cost analysis, service and engineering materials.

“These items are of real value to those studying the development and operation of the airline and aircraft industries,” said Ake. “Flight Path is building an ever-larger collection of aviation research materials thanks to the continuing generosity of our supporters.”

Flight Path’s Schoneberger Library is open to researchers by appointment during the learning center’s regular operating hours, Tuesday through Saturday, 10 a.m. to 3 p.m.

For information, or to make an appointment, (310) 215-5291.

The center and library are in the LAX Imperial Terminal, 6661 Imperial Highway, Westchester.

Admission and parking are free. Flight Path is a nonprofit, community-based organization which operates the learning center, museum and library in cooperation with Los Angeles World Airports, the city agency which operates LAX.
