I'd like to say thanks to CTD for the excellent post, I couldn't agree more.
I've done production, maintenance and developmental test flight work (no experimental) and thought that I knew a fair amount. The group at large on this forum has happily opened my eyes.
We are normally fairly isolated (and insulated) in our work and this interaction, on this board helps to alleviate that.
So likewise thanks to Nick, CTD, Lu, Heedm, helimutt, NR fairy, et al for the excellent and thought provoking interaction.
