Engaging and interesting maybe, but certainly verging on lunacy. Fortunately I have never bought any of their training products, but if I had I'd be finding them now and chucking them in the bin.
How on earth do you descend to 100ft on a pressure setting from over 500nm away. The last pressure setting they had was 3 hours previously and travelling at say 160-180 kts that's over 500nm. They would only need a pressure drop of 4mb to put them into the ground. That's before you even consider whatever the local terrain is.
Also how do you do dead reckoning for 3 hours above an overcast? I thought dead reckoning was calculating a wind adjusted heading and then periodically checking your actual position to your estimated position. You can't do this with no navaids and no visual references. Sounds more like they flew a constant heading for 3 hours in which case they might have been at Sioux Falls or they might have been somewhere very different.
Sounds like a bit of poetic licence to make a good introduction to the risk management stuff.
