A caution that the DFDR on flight 255 was not a Sundstrand
The recorder aboard the Northwest jet, Flight 255, was made by Fairchild Weston Systems Inc. of Sarasota, Fla., one of three manufacturers of such instruments, a spokesman for the Federal Aviation Administration said. according to the New York Times. I am still looking for the TV footage of the reproduction of that trajectory data that was created on a computer display and shown shortly after the event.
