You know what would be a great feature on airplanes?
If each passenger on the airplane was able to find where he/she is at any point during the flight.
When flying, you usually cannot determine where you are, relative to a state or the entire U.S. (or other country you may be flying over). So, why not devise a GPS-type, hand-held device for each seat that allows fylers to see where they on a map.
Yes, I know that the captain will sometimes point out landmarks, but that seems to be more rare.
How cool would that be?
And, maybe charge an extra $5 or so per ticket for all passengers to cover the cost. How much would it really be to implement?
