Canterbury is correct mate. To quote you
30,000ft an hour....wow that must have been terrifying!!!
Wonder if FOQA picked up such a high rate of descent
The article did not say 30,000ft PER hour - it said 30,000ft after it had been airborne for an hour. Quite different.
Can't believe I'm even pointing this out. Actually I can't believe Canterbury had to point it out to you and that you chose to have a dig at him because you STILL didn't get it. ICAO English level 2 for you.
