TC, sorry to break it to you, but the CH-46 accident wasn't even SWP. It was merely a misjudged approach. He probably had plenty of power. But he screwed up. His approach angle was nice and constant, but the boat was moving up and down - something obviously not taken into account. The '46 pilot came in way too shallow and caught a wheel on the fencing. Oops! Happens. It's why PHI taught us to come into oil platforms steep and slow, never shallow and fast - just for that reason. Worked for me.
To those of you who say the US FAA is wrong about this or that...well...whatever. If it makes you guys feel superior or something, that's fine.
If you guys want to narrowly define SWP as something other than VRS...well...I think y'all are wrong.
