An article on why TAS is so important with regards to flutter.

Thanks for the article on flutter. Although I thought I had a fair understanding of flutter lurking in the deep dark recesses of the remains of my mind, this article explains the phenomenon in an orderly and coherent manner. Every day, I learn that I'm not too old to learn sumthin'. It seems that my understanding of flutter was a bit muddy ... at best.

This article allowed me to understand why at an altitude of 70,000+ feet, the separation between V/S (stall) and V/NE (never exceed) of the U-2 is only around 5 knots. I can't imagine cruising around in the days of nuthin' but steam gauges and INS (no GPS) for hours in a U-2 flying in that narrow of an envelope. I'd be shakin' like a puppy passin' peach pits in a hail storm.

Cheers,
Grog
