I think I can speak for all the beta testers in saying that we appreciate the thanks of the community. Beta testing A2A aircraft is not an easy job, nor a quick one but it is immensley satisfying and challenging.
I know I have said it before but the bredth of experience in different areas (and often for real on the specific aircraft or ones VERY similar) amongst the testing team is amazing, as is the range of different skills and interests. Personally, I couldn't spot a spellung mustike to save my life...but some guys can pick them out on gauges that my old eyes can hardly see!! Some pick every small graphical problem or colour mismatch. Others are anal-retentive enough to climb a Spitfire through three or four full 30 minute test climbs on every single beta release, keeping full records of boost, rate, speed, rpm etc etc every 500 feet. Then do speed and dive tests as well (although I couldn't possibly comment on who that may be

) Yet others specialise in blowing up engines...some of those even do it deliberately!! Some guys test every single aircraft from the first beta to the last, pulling it apart down to (quite literally) a nuts and bolts level.
Even Amanda/Felicity/Bruenhilde (or whatever she is calling herslef today) finds something once in a while!!
I also know how hard everyone takes it when something does slip through. However I have been involved in projects 1/10 the complication that have 10 times the problems on release..and this is directly because of the factors that Wiqvist mentioned above.
Anyhow, cheers guys!
