I flew on a C-130 once. It was a deployment ride on 19 January 1991 that began in a chilly 0°C Hamburg, Germany airport on said airplane in which the heater was broken and then landed in King Fahd International Airport at around 1 PM local, which by then was above 30°C, and as we were exiting the plane carrying our ruck sack, duffle bag and all of our cold weather gear that we had been wearing and then they handed us a each a case of water to carry as well...good times...
Good old pre planning by the brass lol!
