Boeing Modifies 737 for Operations From Short Airfields

Seattle—Boeing Co. has demonstrated to the airlines a short-field version of its twin-engine 737 transport capable of operating into 4,000-ft. runways to determine the demand for a jet transport of this type. Airline evaluation of the modified company-owned 737-100 began in April and was nearing completion early this month.

Experts Struggled to Control 2707 Weight

San Francisco—Industry weight engineers were told here recently that their best efforts were insufficient when it came to estimating the weight of the Boeing supersonic transport early in the design process. USAF Maj. Gen. J. C. Maxwell, director of the Federal Aviation Administration’s supersonic transport effort, said the serious structural weight problems that forced redesign of the aircraft provide a lesson “in the area of estimating the weight of an airplane during preliminary design."

Nixon User Tax Plan Drops Trust Fund

Washington—Compromise approach by the Nixon Administration to airport/airways development funding will link user taxes directly to improvements, but without establishment of a trust fund. An Administration bill is being re-written by Transportation Dept, officials to meet Budget Bureau and Treasury Dept, objections to the trust fund concept which they rejected earlier (AW&ST May 5, p. 21).

Rockets Bolster Dc-9 Payload Capability

New York—Standby rocket power enables Overseas National Airways (ONA) to increase the payloads of each of its four McDonnell Douglas DC-9-32Fs by as much as four tons. The supplemental airline is the first carrier to install such rockets on a turbofan transport, according to ONA Capt. L. R. Furlong, who had a major role in obtaining Federal Aviation Administration certification for this installation.
