I thought we were using those big black triangular blimp things to do all of the heavy lifting....
Oh wait....that was a secret. Never mind.
Yeah! THOSE big triangular things that are based at Tinker AFB in Oklahoma! They actually get a more kinda rounded shape when they're full of stuff! My dad sees dozens of 'em every day from his house! They fly as fast as C-17's!
(Hey... is it okay to talk about this kind of stuff?)
