Names? What were they flying? What was the cause? > Anything. 0200 local time, 11 Jul 1986: MAJ Ross E. Mulhare, flying F-117A serial 81-10792, callsign "ARIEL 31". Possible cause was fatigue due to the sleep schedule that F-117 pilots were required to keep while the aircraft was still classified (and restricted to flying night missions). This was the first operational F-117 loss. 14 Oct 1987: MAJ Michael C. Stewart, flying F-117A serial 85-01815 on a night mission over the Nellis gunnery range, callsign "BURNER 54". Cause may have been disorientation due to fatigue, the same reason for the loss of Mulhare. Incidentally, the 4450th lost another aircraft less than a week later, on 20 October 87. This was the A-7D Corsair II which crashed into an Indianapolis hotel after the pilot, MAJ Bruce Teagarden, was forced to eject after losing the engine. The connection to the F-117 program was never made in the open press. Hope that helps. ____________________________________________________________________________ Robin J.
