Drones are in, just ask an armed forces general or other delivery specialist.
Need a 50-ton tank delivered in the middle of the tundra? No problem. Or need a few containers of Christmas ribbons at the North Pole for Santa and his Elves? No problem either.
If you aware of the up and coming things, the latest development should not surprise you: Super-Drones (SDs, my terminology), also known as large blimps or, decades ago, as "Zeppelins."
