F-89J Scorpion No. 53-2547



F-89J No. 53-2547 took off from Indian Springs AFB on 1957 Jul 19 at 1305 UTC and flew to the Nevada Test Site. It fired a Genie MB-1 missile with a live 1.5 kT W-25 nuclear warhead which at 1400 UTC (0700 PDT) detonated 4.2 km downrange, 6 km above the test site. The plane landed at Indian Springs at 1407. This was Operation PLUMBOB shot JOHN. Indian Springs (now Creech AFB) has two runways, 13/31 and the large 08/26. My guess is that the larger runway is relatively new and the 1957 flight would have used 13/31.
