Show us the track and the GPS log. And they better be showing us a stable and sustained speed track with consistant coordinate points.
Currently I got two tracks showing a F16 did 110 km/h and 400 km/h. Both were GPS measurement glitches like Rolf said. Every now and then a GPS receiver miscalculates a point, sometimes even by several hundred meters (hence the over 400 km/h speed recording ! The boat was actually stationary on the beach at the time)
So don't give us smack talk just give us proof !
