Cessna 337 Skymaster crash.

Where did you get the flight track data? Is it from a web site? If so, what is that web site and will it work for any flight within the USA?

I find it very interesting that the last few minutes of flight were erratic in altitude and speed. It doesn't look large enough to be a T-storm, but it certainly might show trouble with aircraft control...VFR in IMC conditions, etc.
