NOTE 1:  Totals do not include one Atlas-Able destroyed on Cape
pad LC 12 during static engine test on 9/24/1959.  This Atlas 
(9C) was not actually "launched", and is not included in most 
historical Atlas launch summaries.
NOTE 2:  Failed AC-1 launch was a planned suborbital flight.  
Totals also do not include four Atlas ICBMs destroyed in ground 
accidents (one in 1963, three in 1964).

NOTE 2:  Suborbital ICBM flights.  Does not include one 
Titan 1 (V-2) destroyed during launch rehearsal in 
Vandenberg Operational Suitability Test Facility (OSTF) 
on 12/3/1960.  Cause was failed control valve in silo 
launch platform hydraulic elevator system.  This Titan 
was not launched and is not included in most Titan 
launch summaries.
