Smile Re: Air Crash Confidential

I have seen several of these and the scenes are staged by rather non technical personnel for an audience of generally non technical people.
If you look at some you can spot oscilloscopes on shelves or the background that are free running with no probes connected or connected to the cal output and have nothing to do with any sort of fault investigation but just to make a investigation lab look interesting.

I would expect real crash investigation labs to be rather dull looking and not have flight critical components rolling around desks!!

There was one programme where a critical hydraulic actuator froze causing a crash in which it was tested by supposedly cooling it down on a test rig by someone stood next to it blasting it with a CO2 fire extinguisher to make it very cold! not very scientific and was waiting for the chap to keel over after breathing in all that CO2!!!
