Maybe we should wait for the FDR numbers to come out. I don't want to be anally retentive but the data put forward by Koring doesn't seem logical.
A STRAIGHT-IN approach with an initial step-down from FL 345 to 130 in 9 minutes covering a distance over the water of 137-13 km = 124km at a TAS of about 450kts.The rate of descent sounds achievable but 450kts?
Then the final 13km travelled in 12 minutes, meaning he did get within spitting distance with plenty of altitude that then needed to be bled off, belying the straight-in theory.
Sounds more like an excocet missile with a parachute than a scarebus.
