Officials from NASA and the Lockheed-Georgia Company, Marietta, Georgia, announced that flight testing had begun on a new, highly fuel efficient, "propfan" engine. Aircraft equipped with the propfan propulsion system, which was developed as a result of a $56-million NASA sponsored research program, was expected to be 15-30 percent more fuel efficient than the most advanced turbofan-powered aircraft flying in the 1990's. (NASA Release 87-73)
The Soviet Union launched another cargo ship with supplies for the space station Mir. According to Tass, the cargo ship Progress 30, the third supply ship launched since cosmonauts Yuri V. Romanenko and Alexander Laveikin had occupied the space station in February 1987, was functioning normally after the launch. (LA Times, May 20/87)
