I was a passenger on a C5A Galaxy back when it was the largest cargo plane in the world. Looks like this thing could carry a few C5As in it’s cargo bay.
Why then Antonov AN-225 wasn’t called to haul Saddam Hussein’s 550 metric tons yellowcakes directly to Canada? It took 37 C-17 top-secret flights from Baghdad to Diego Garcia then shipped on SS Gopher State under heavy security to Canada. Under heavy security? Oh it was low-grade yellowcake, yeah right. How much yellowcake to make a U-235 anyway?
