An very enjoyable programme, and respect to the people who do such work.
What a shame they felt the need to 'jazz it up a bit' with such nonsense as the 3,500 horsepower engine they carried on the skids to power the pressure washer - it looked just like the 3.5HP model I am familiar with, especially when carried easily by just 2 of the crew.
If that little portable engine/pump produced 3,500 horsepower then we're all idiots, and the world's energy problems are miraculously solved at a stroke.
Or maybe he was just confusing PSI with horsepower...
