How about a C130 with 6 JATO Rockets installed....would that be 1,2,3,4,J1,J2,J3,J4,J5 and J6 (?) although I believe with all the terrorist guff happening, the numbers are randomly reviewed hourly and new assignment combinations are issued to each crew 5 minutes before startup (and can be changed in the air if a threat exists.)
Can get quite scarey in the chocks if you fire up J3 instead of the APU!
