It would be nice if wildcards could be used in the tail number field. This would let people do things like track all Angel Flights. Angel Flights file with the prefix NGF. For example my Cessna, N8035G, files as NGF35G. It would be great if entering NGF* showed all flights using the Angel Flight call sign.
Many other operators use callsign prefixes, this would have a lot of applicablity in the aviation community.
Thanks for a great service!!!
