After the great disaster in the Himalayan region in India, I found roads had been washed away and Indian Air force / Army had to be called in with helicopters to airlift over 1 lakh pilgrims to safer areas. Anyone would know the scale of this operation - especially considering that it was continuously raining, shelters had been washed away, there was no food for survivors for nearly a fortnight. Air dropping food was also risky for helicopters in that weather condition. Rescue effort was slow and that was the only option too. This massive operation involved many sorties of helicopters over more than 20 days.!!!!
Hence I decided to search through Airships, hot air balloons used for rescue missions. On the one hand hydrogen balloons are not safe, helium is not easily available for balloons. is there any such low cost easily inflatable air borne rescue. large scale solution possible- even in poor weather- other than helicopters- to operate - where even pick / up landing facilities may not be available?
