Cool new airlift capability in use

Chris Taylor discusses why the newest military transport aircraft in the Canadian Forces is a good thing to have:

Each Herc carries a crew of five — 2 pilots, 1 navigator, 1 flight engineer, and 1 loadmaster. That's fifteen people to move these pallets, or a week of duty days for a single aircrew. The Herc would make each 1,568nm trip in 6 hours — that's 12 hours including the return trip. So for a single CC-130H aircraft to move these 13 pallets, it would require three 12-hour trips, or three aircraft making a single 12-hour return flight. Not including ground handling, offload and refueling times.

In contrast, a single CC-177 can fly all 13 pallets to Jamaica in 3 hours, 49 minutes, using a single aircrew of three (2 pilots, 1 loadmaster). And it can carry sufficient fuel for the entire journey. Tack on the return trip and you have the entire mission completed in just under 8 hours, not including ground handling and offload times.

Remind me why the CC-177 isn't the best choice in this scenario?

I do find the formal military designation to be a bit odd: CC-177, rather than the American designation C-17. Even the defence minister calls it a C-17 in public. It looks like somebody stuttered while typing up the original name.
