// Dry Mass: 430 lb
// Thrust: 50,461.5 lb vac -- the technical data reference mentions 59klbf vac thrust for M5, which is likely a typo for 49klbf. Later it mentions 43.4klbf "vac" thrust for M5E1 but that does not jibe with other references reporting 43.4klbf takeoff thrust (technically x4, since clustered)
// The NASA sources mention 42.5klbf, which again seems correct for liftoff thrust rather than vac thrust given the thing only burns 3.4-3.5s.
// So use 3.5/3.4 (which equates to 43.4/42.143) * 49,000 = 50,461.5 lbf
