Does it have an intended purpose other than super size balloon flights?

Not really a secret spy vehicle is it?

A 747F carries 10 times the payload and goes about 10 times faster.

Looks like just another episode of Monty Python's Flying Circus.

A 747F will not land anywhere near where the AirLander can. Disaster relief? check!

Remote mining or oil recovery operations? check! Luxury tourism? check!

Loiter high over an area for days? check!

I do wonder about the so-called 5 day flight duration limitation, and what the reason for this is, could it be crew and passenger accommodation is only for 5 days? Or it is that she lifts off with 5 days worth of fuel.

I know helium was chosen due to safety reasons, but why wouldn't hydrogen do just as well? I think hydrogen molecule is larger than helium atom, and thus should not leak quite as fast through the same material.
