http://www.nytimes.com/2002/11/08/politics/08RADA.html A week or so ago I was passing time looking at the 10 minute delayed display of traffic to LaGuardia on http://www4.passur.com/lga.html I clicked on the symbol of an aircraft flying south along the Hudson River around GW bridge. Its altitude was given as 1100 feet or so. As I watched it meandered a little to the Jersey side and descended a little. Then its type identification changed. I forget the detail, but it was initially identified as something like E135, but abruptly changed to something like D93. It continued south for a while, then turned east as if heading to JFK. Now its ident changed again to some other aircraft type (I can't guess what some of the three character identifications mean) and it flew on, passing north of JFK still at moderate altitude. I wonder if STARS is subject to some of these peculiarities?
