We ran into an interesting issue using Airtribune Live Tracking
track logs for scoring purposes with FS. Airtribune has a switch that allows 
Live Tracking to ignore landings. So if you land and relaunch (we had many
today) Airtribune treats both flights as a single flight.

FS apparently doesn't digest this well. Lots of Airtribune Live Tracking track
logs that looked perfectly fine in SeeYou did not work well in FS.
