Speaking of Flutter, did anyone catch the video taken from inside the Qantas Air Bus 380 that had the engine explode. I caught a brief glimpse at 10am PST on one of the news channels and when I came in to the PC to see if it was on line, I found a link, but it wouldn't open and now it's gone. The shot was back onto the wing from the cabin and it looked like spoilers were deployed and they and the TE was were doing quite a dance.Sure wish I could find it again.

By the way Mike, great article. Well explained. A couple of our guys, actually about 10% of our club are active in the aircraft industry, retired from it, or teaching at Cal Poly. I'll link to the article on our web site if it is OK with you. Some of these guys like to debate things like this and at times debate themselves. It will be interesting to see their comments. Myself, KISS. I don't need to know all the thrust vectors and calculations. It happens and your explanation is spot on. By the way, We have a large Guitar store in town. Imay have to give you example a try
