The most downloaded plane (on flightsim.com, that is) is the AA 727 as mentioned above. The most downloaded file in general is the FS98 FSFSConverter. As many of us know, you had to have that file to add 3rd party aircraft. Because it is essential, it is cheating a bit, but there have so far been 192,392 downloads 80 !!!
