Pan Am went to great lengths to build up the infrastructure for its TPAC Clipper services...including setting up the then-desolate Wake Island among other Pacific stations for refueling and resupply.

But such will be necessary for various space travel needs in the future. A brief article on the early Pan Am setup days:
