From the Sooeet thingy....
The ground speeds shown on Figure 2 should be at most 4 knots above the indicated airspeeds that the crew of the accident aircraft would have seen on their cockpit instruments. This is due to the fact that the prevailing low level wind (a tailwind), was at most 4 knots.
Not unless you ignore the 2% per thousand difference in indicated versus true airspeed.
Which you can't.
