Capvermell you blinking idiot.
I would not begin to speculate on what caused the current position the Northern Rock building soc has found itself in because I know nothing of finance. Your ridiculous comments about vortex ring and passengers distracting the pilot sound to professional helicopter aviators like if I started making up reasons why NR are in the poo on a financial analyst discussion forum. I would not do it as it would result in my own ridicule......and I would certainly deserve it. Please please go and spend some (or a lot) of time reading about rotary wing aviation and I will go and dig out my old GCSE economics text books in return.
At very least do a search on vortex ring and start reading. It was my understanding that finance is all about speculation.............aviation is based mainly around large servings of fact backed up by experience. Keep the speculation to the works canteen.
