A thread popped up on FT concerning the tracking of an individual AC:
I cant imagine tail numbers not being reported on FP’s for scheduled commercial service. Can this be extracted from the FAA database? Maybe you could post the tail number on the flight info page. An additional feature could be tying the hull history info (as found on planespotters.net) to the tail number on the flight info page so all of this stuff could pop up with one or two mouse clicks.
