Flight Test Program for L-1011 Realigned

Los Angeles—Delays and uncertainties in Lockheed’s L-1011 transport program have prompted the company to realign its flight test schedule somewhat, and eliminate one aircraft from the original six-aircraft flight test contingent. Performance and propulsion tests planned for the second L-1011 have been put off up to this time because of the lack of fully powered Rolls-Royce RB.211 engines.

Another Progress Payment

The sad death of three Soviet cosmonauts in Soyuz 11 is another progress payment on the ultimate price of man’s unceasing quest for new knowledge. Lieut. Col. Georgi T. Dobrovolsky, Flight Engineer Vladislav N. Volkov and Test Engineer Viktor I. Patsayev were pioneering a new phase of space flight not only by working in the first prototype of a true orbital space station but also in extending the period of man’s operations in the environmental conditions of space.
