Sounds nightmarish in a Kafkaesque kind of way, and is very sad.

Guys, IUCRR have been doing a very good job at collecting data at the rescue and recoveries they were involved in. They're well trained, very experienced, and have a sound protocol in place.

Just have a look at their website, this is likely one of those few times when some usable data actually is collected and becomes available.

Hats off to the recovery team, and condolences to the family and friends of the victim.
