I wish I had the confidence in the industry to tell you, but I cannot help thinking that there are some on this board who would delight in making my life more miserable because I dare to speak out against what you obviously enjoy doing.
In fairness to L&L, I don't think I'd put my exact location on a forum like this if I were complaining about noise...Piss Off Biggles anyone?
On the subject of how worthwhile the flights are which pass over L&L's house (which his neighbours say is getting worse over the years), maybe the recession will have a beneficial effect (in terms of noise, because fewer people will splash out to go by air). Presumably, with the economy in tatters, every private helicopter flying must be doing something pretty worthwhile or carrying someone pretty important?
