I have always wondered what the line going from the tail to the top of the cockpit was for.....anyone?
Well actually since Transport Command don't utilize the quickest of all flying A/C, some long distance trips can get quite time consuming, and hence the crews need to hang out their laundry after wearing the same uniform for these extended periods......its hard work sitting in one plane for a long time and you can really work up a sweat..........
.......................its probably an antenna ?
