Anyone care to share their thoughts about Airborne Wireless Networks?
I see advantages and disadvantages.
  1. Fairly low cost to cover wide areas.
  2. Long range from high frequency signals.

  1. Inability to assure 24/7 coverage in many areas. Airlines fly fixed routes.
  2. Total shutdown in the event of a national ground-stop (e.g. 9/11)
  3. Airlines will demand a premium to carry the gear, regardless of usage.

Perhaps best as a lower-cost non-mission-critical substitute for satellite. The problem is that planes are not actually always overhead everywhere.
