It is said that what goes up must come down.
Last month, six W80-1 nuclear-armed AGM-129 advanced cruise missiles went up from Minot Air Force Base, N.D., and came down in Barksdale AFB in Louisiana.
Did six come down?
This news story reports that it was 5 nuclear warheads: See Here
Are we missing one?
In this analysis of the event Explosive Implications the care with which these bombs are handled is elaborated. That would seem to make answering this crucial question as simple as the math involved.
Curiously, "Six members of the US Air Force who were involved in the Minot AFB incident, have died".
Here are the details of those six whose tales will not be told:
1. Airman First Class Todd Blue (Cause of death not released)
2. Airman Adam Barrs (killed in a crash)
3&4. A "married couple" from the base (killed in a crash)
5. First Lt. Weston Kissel, 28, a Minot Air Force Base bomber pilot (killed in a crash)
6. Air Force captain John Frueh (body found near Badger Peak in northeast Skamania County, Washington)
Move away folks. Nothing to see here...
