Letter to the editor of the revered
NT News on May 24 from the chair of an aviation safety group put a good slant on the reality of said incident.
A letter from one of the pax, in the NT News
of 29th May basically told the author of the letter of the 24th that he didn't know what it was like
descend from 27000' to 8000' in "30 seconds" ! 
Now the 146 might be a capable aircraft, and despite some light hearted ribbing I do believe it does what it does quite well, and one of its better points is going down, but I ask you ..... 38,000 feet per minute rate of descent? I don't think so.
