Whirl Mode Is Linked to Electra Accident

N 9705C was a new aircraft. Its final assembly was started in April, 1959, and the first of its three production test flights was on September 4, 1959, 25 days prior to the accident. Braniff Airways accepted delivery of the aircraft at the factory, Burbank, California, on September 18, 1959.

Sabreliner Shows Fighter-like Handling, Performance

Edwards AFB, Calif.—North American's T-39 A Sabreliner is comparable in size and weight to the F-86 and, with the exception of a lower maximum Mach number, performance of the new trainer/utility cargo jet transport is very much like the performance of the Sabre fighter.

Mooney Mark 21 Shows Performance Gains

New York—Improved flight characteristics of the all-metal Mark 21 is an unexpected boon for Mooney Aircraft Co. and adds justification to its switch from the wood-and-metal construction of the Mark 20. Mooney engineers believed that conersion from the wooden wing and empennage of the Mark 20 to the all-metal construction of the Mark 21 would have no influence on the performance of the new aircraft inasmuch as the physical and aerodynamic dimensions were identical.

French Introducing Medium-range Stol Transports

Paris—French aircraft industry, in a bid to strengthen its foothold in the transport field, is introducing a series of medium-range aircraft with STOL characteristics as a means of filling the gap not covered by foreign competitors. The new aircraft, stemming largely from designs developed under competitive bidding for a military contract, will be offered in both cargo and passenger versions.

V/stol Proposals Dominate Paris Show

Paris—VTOL designs, proposals and politics were dominating factors at this year's Paris International Air Show at Le Bourget Airport. The show had only one flying VTOL test vehicle on hand, the Short SC. 1, but the static displays and technical conversation at the exhibits emphasized Europe's growing interest in a family of V/STOL aircraft.

Space Program Will Cost $25-30 Billion Over Five Years

Washington—Total national spacc program over the next five years will cost $25-30 billion, and the civilian space budget will reach a $4-5 billion annual level by Fiscal 1963 under the current Kennedy Administration plan. The Administration already had planned to spend an estimated SI 5-20 billion in the next five years but had not revealed the figure.
