The B-1 uses ACES II seats. There are several "options" available as to "command select or individual select' but the system still "manages" the sequence of firing each of the four seats, to prevent any "conflict" so no seats will fire in a situation that likely result in seats firing where any "collision" (conflict) will occur...
