Exactly, it’s been SOP to develop all rolls of film found in airliner plane wrecks for decades - bringing it up to date, why not look in every cell phone?
I noticed a show on weather channel last night covering the Air New Zealand Flight 901 disaster and it showed film recorded near the end of the flight. Very sad to realize all those people shown were just about to die - at least they didn't know it. Only the cockpit crew had a few seconds of warning. To sit there for a few minutes as the aircraft inexorably descends to your death has got to be like walking down to death row to be executed. Especially when you realize there will be no reprieve.
