[edit] critical mach number verses drag divergence mach number
the article says that the critical mach number was responsible for the so called "sound barrier," I was under the impression (I'll get sources later) that the sound barrier was caused by drag divergence. That is the sound barrier was caused by what looked like an exponential increase in drag that many guessed would go to infinty as mach 1 was approached. This wasn't true.. drag levels off and eventually decreases. —The preceding unsigned comment was added by Cole.christensen (talk • contribs) 07:55, 11 December 2006 (UTC).
