the lines were the antennas) I don't remember if they used helium or
hydrogen to get the balloons up into the air.They had the lines of the
balloons attached to big wooden homemade reels.They would let the
balloons go up into the air and when they were through doing their
transmitting or receiving of broadcast,they would reel the balloons back
down.I read about that in a Saga or Bluebook for Men or a True magazine
(I don't remember which magazine it was) back in the 1950's so I might
not have all of the details of the article in the magazine exactly
right.It has been about 55 years ago since I read that article in the
magazine.
