The biggest issue is the inflation rate.The people who wrote that article are dumber than I expected. Yes, if they could slow themselves over some number of inches they could survive, but foam from a fire extinguisher inflating a body bag isn't going to accomplish that.
In fact, all diesel locos are electric. No power from the diesel generator means the actually train motors won't go. I'd be careful of what you mess with electrically on them though. We're talking about enough electrical power being generated to pull a train, after all.By the way, since many diesel trains are actually diesel motor driving a generator, then that electricity is used for electric traction motors, why didn't MacGyver disconnect those power cables after the engine was sabotaged to go full speed, rather than going through all the troubles of trying to disconnect the passenger cars from the engine, and then later end up rewiring the power cables to run the traction motors in reverse? Or easier yet, flip off the circuit breakers or pull the fuses (like, maybe, in the panel behind where the engineer sits)? (Then there could be a second encounter with those trying to kill the witness or, sigh, room for even more commercials.)
Well, if they could inflate the bag with foam from a fire extinguisher there's still a fundamental problem of energy release or dissipation. The bag has to burst in a controlled manner to gradually slow them. If it doesn't burst they bounce off having been given back most of the energy in the opposite direction like a ball bouncing on the ground. That's bad. If the bag bursts easily and offers no resistance it won't slow them down. That's also bad.The biggest issue is the inflation rate.
A fire extinguisher would take a good minute or more to inflate something the size of a body bag. You would need something more along the lines of the explosive inflators airbags use to get that immediate inflation.
Further, the whole stunt is predicated on the extinguisher being either foam or C02. Most extinguishers in a factory environment like that use multi-purpose dry chemicals, not foam or C02. In other words, they would be filling the bag with propellant and a coating of powder.
They would have been better off making parachutes out of the bags - or using them to make a rope to climb close to the ground.
I didn't think it was in reference to one of the A-Team members (the one who was crazy), so I did a quick Google search and came up with this in context of the 1985-92 MacGyver series: https://en.wikipedia.org/wiki/MurdocThey revealed the name of his adversary "Murdock" like it was a huge reveal/stunning moment. Anyone want to fill me in/ (I never saw the original if that is what it was about).
Murdoc is Angus MacGyver's most frequent opponent, a member of Homicide International Trust (HIT) and master assassin who never fails – except when MacGyver gets involved.
