Project Sunrise Prototype # 2

The Lockheed project office and DARPA suggested that the excess climb power would be better spent charging a battery for night flight rather than to rely on glide only. Astro Flight was instructed to submit a proposal for a follow on version of the first prototype aircraft.

Roland Boucher prepared a proposal to Lockheed for a follow on version which would use a higher efficiency solar panel. The new solar panels would produce more power, and because they were much were smoother, would produce less aerodynamic drag.  This proposal was accepted by Lockheed in the spring of 1975.

Mr Roland Boucher had become physically exhausted from the strain of developing project Sunrise. He suffered from Congestive Heart failure and was placed in intensive care in Santa Monica Hospital. Before leaving the hospital he resigned from Astro Flight and  sold his interest to his  brother Bob Boucher.  After recuperating for a number of months he returned to Hughes Aircraft Corp where he was assigned to a classified military program.
