The report describes POBAL, a test flight to demonstrate the feasibility of accomplishing station-keeping by powering a 711,000-cu. ft. free balloon against the wind in the minimum wind field near 60,000-ft altitude. The propulsion system, fabricated from off the shelf components, incorporated a 35-ft diameter helicopter rotor and an 8-hp electric motor powered by Ag-Zn batteries. Line of thrust was controlled by a 9-ft high rudder, steerable either by radio command or by autopilot. POBAL was flown from Holloman AFB, New Mexico in September 1972. System components, flight results, recommendations and feasibility studies for a long duration POBAL system are discussed. (Author).

Preface: in the past few years there has been much discussion both In the United States and abroad of the ability of Lighter Than Air vehicles to meet future transportation needs. Many of the proposed uses and missions seem promising. However, Lighter Than Air Is not without Its problems. Although modern technology may be able to overcome these problems, the ultimate Issue could be the economic feasibility of Lighter Than Air.

The annotated bibliography has evolved from an informal compilation prepared in response to many requests from military and civilian researchers who were planning balloon-borne experiments and searching for data or detailed information concerning some specific aspects of modern scientific ballooning operations. The bibliography consists of three parts: a subject index, an author index, and the bibliography with annotations.
