Military Navaid Has Special Civil Uses

Denver—Small military Tacan terminals are demonstrating their ability to meet specialized civil needs where conventional civil navaids cannot operate satisfactorily because of difficult terrain, or for a variety other reasons. The first full-time civil application in the U. S. is a recent installation at Aspen, Colo., where an AN/TRN-26 mini-Tacan has had a notable impact on the operations and profits, of Aspen Airways, whose principal market is flying skiers between Denver and Aspen.

Helicopters, Streetcars Sharing Facility

Philadelphia—Advanced technology streetcars are starting to move down a high-bayfactory assembly line in a former locomotive plant here that also houses Boeing Vertol Co. CH-47 Chinook helicopter assembly.
