Yes this sentence is in the final report but you have to remember the following ( explained in the report )
Visibility was between 150 and 200m and collision occurred more than 2Km away . The citation was cleared via a taxi way taking it to the north of the runway ( away from it ) , and the pilot had confirmed that route. The SAS was on the TWR frequency and was supposed to take off and not call back within a minute or so. So there was no reason for the controller that made that remark to realise that there has been a crash and that the sound reported was indeed that of one.
Of course with the benefit of hinsight, it was an unfortunate joke. But only then.
In many Accidents reports such sentences are marked as "irrelevant "and not printed as they do contribute in any way to explain the accident and only upset the famillies of the victims.
I am surprised they aired that tape to the famillies... This is shocking indeed.
