Remote Propeller Drives

With the impetus given aeronautical design by wartime exigencies and the consequent demand for optimum performance without regard to normal considerations of conventional practices and cost, attention of designers again is turning toward the provocative problems of "piping" propulsive power from powerplants to most efficient locations for propellers. Here is a review of progress in this field to date

Airline Progress and Mail Rates

WHILE the airlines show another year of progress in their 1941 annual accounts, the dominent note appears to revolve around the question of mail compensation. Either a protest is leveled against the threat of reduced mail pay or notice is served that increased mail compensation may be sought.
