    I was wondering if anyone has the flight data for both flights 11 and 175, or has a link from where I can download it.

    I'm after the flight data for both flights 11 and 175 from takeoff to impact, that is (lat,lon,alt,speed) at all time points. From the ntsb flight study reports I can lookup the altitude for a given time and hence could get by with (lat,lon,speed).

    The ntsb flight study path documents have minimal information of crude looking flight paths and (alt v time) graphs, and I'm after much more detailed data.

    I gather that this data was avaialble a while back via .csv files but I can no longer find it. I've tried contacting a few different people, but no one emails me back!

    Thanks for any assistance.

    That's great - thanks. I'll be able to parse the .kml for what I need.

    I extracted the flight path data from the cited .kml file and noticed in the case of Flight 11 that the timestamps increase up to 08:02:40 and then drop back again to 08:02:04, which is 36 secs before. After 08:02:40 there are another 5 timestamps until we arrive at a point in time that is great than 08:02:40; namely 08:02:52:

    I'd suspect that's due to overlapping data from two different primary radar stations.
