That's interesting... is this the same Steve Matchett who was a member of that ill-fated pit crew at Hockenheim in 1994 where race winner Max Verstappen's father Jos was flambéed?
Indeed. He was either on the rear jack or holding the starter (I can't remember which.) Wrote a great book called "The Mechanics Tale" and is generally a really good add to the US commentating team.
As I recall, he got a three or four race fill-in deal when Speedvision (or was it ESPN) was the US network for F1 in the 90's. He brought so much to the team in contacts and understanding that they added him on full time. Remember that was back when we were lucky to get the world feed in the US and never saw driver interviews (aside from the podiums) or any technical content. (Come to think of it, they also use to stack a replay of qualifying in front of the actual race on Sundays. That worked out OK in the days before push news on the internet.)
If you are really interested (and you're probably not...) dredge through the archives of RASF1 on usenet. There was massive chatter around "who is this new guy and he really knows his stuff" when they added him.
FWIW

PS, Not really a case of "ill-fated" as no one was actually hurt badly in that fire. I think the fuel hose guy had some lung/airway issues because he had jimmied his mask and defeated some of the safety features. There are lots of spectacular pictures but he whole thing lasted less than a few seconds. It is on youtube.
