 F1 was launched successfully on November 8, 1984 aboard STS-51-A.This was followed on April 12, 1985 by Leasat F3 on STS-51-D. F3's launch was declared a failure when the satellite failed to start its maneuver to geostationary orbit once released from "Discovery".Attempts by Shuttle astronauts to activate F3 with a makeshift "flyswatter" were unsuccessful.
