The transmissions imply that the aircraft was airborne at each of those 3 points (our antenna can't normally detect aircraft 7nm away on the Blackbushe runway), but clearly that's not enough data to construct a deceleration profile, nor to deduce where the Phenom may have touched down and/or become airborne again.
In case anyone should be wondering how we captured an airborne position 850m beyond the threshold (140m beyond where the aircraft touched down, as the AAIB graphic shows), I have to confess that I don't know.
