I wonder, technically, if you can do drops from a AN-124?
Nope, I was told by Viktor Tolmachev (he designed it) that only a couple of the prototypes did air drops. Clam shell doors flutter if back is opened when airborne so would need beefing up and re-certifying.
Could always rent Volga's Il-76s though.
Or, call me radical, chuck the meat bombs out of a C-17? What? Not cleared?
Boscombe, mumble, paperwork, lease terms, drivel, etc.
