It would be pretty close, but of course not timestamped as you would get from the DFDR or QAR. The 88kts would have come from the GPS receiver, so turning GS into IAS/TAS needs the wind component, as I recall the wind was a low figure (10kts approx?) from 210 degrees so about 25 or 30 degrees off the runway heading. That might make the IAS another 8 kts or so higher?
I wasn't intending to do anything other than provide what I believe to be quite accurate information, or point any fingers. In comparison with some of what has appeared here today I thought it was pretty tame actually.
