JFD,
Could fall into a trap revealing which part of the country I'm from ( you could be Walter !!) I do all I can to encourage my part of the world to read not only our private forum but Engineers as well. Those that contribute here must be a small minority. Look at the military pilots, continuous inputs 24 hrs a day. Wonder if PPrune have any advertising material we could post on notice boards etc to encourage more Engineering membership.
