I'm unable to post an audio clip (4.15k) to the new style forum.
The following error message comes up
413 Request Entity Too Large
Problem resolved (thanks Dave) and clips now attached.
This first clip is from the Tower feed apart from the short section when Cessna 992 briefly switches to the Ground frequency to give directions to vehicles searching for the downed aircraft.
The second clip is from the Ground archive.
Details including photos here
