I attended this course in Torrance at the same time as headsethair and agree with most all of his comments (that R44 video is a real frightener since the guy has several opportunities to avoid disaster but just doesn't).
Only thing I have to add is that the rules (US at least) concerning passengers and instructing in the R22 are stated in SFAR 73 of title 14 of the Code of Federal Regulations; the figures quoted by Headsethair were shown on the course, but I believe these were presented as insurance company requirements, not legal requirements (in the US at least)?
