2) delivery of relief supplies to conflict / disaster zones.
I have no idea if the hull of Airlander can withstand AK47 bullets, but having worked in aforementioned zones for years, I know that it would make a great target for some crazed kid with an AK. Better rule that one - largely - out.
Not all disaster zones are full of AK47 wielding hooligans. Just look at the size of the UN operation in Africa alone, I can easily see the AirLander fitting in there - For example based at Entebbe, capable of providing relief flights to Sudan, Congo etc where runways are extremely limited and of very poor quality. An AirLander full of aid pondering across Uganda over into Congo would be ideal.
3) delivery of heavy/outsize equipment to remote locations.
This one might work, although many / most remote locations also experience inclement wx to which this machine seems to be quite vulnerable.
Delivery of equipment to remote locations in Africa, oil field in the Middle East, the mines and oil/gas fields of Siberia/Russia. A perfect candidate IMO.
