The speed of sound (Mach 1.0) varies with temperature; lower temp equals a lower TAS value for Mach 1.0. Tony's using standard atmosphere, which assumes a linear temperature lapse rate of 2 deg. C/1,000 feet from sea level (+15 deg. C) up to the tropopause (nominally at 11,000m/36,089 ft.), where the temperature stops falling (in the stratosphere it starts increasing again). At sea level, Mach 1 is around 661 kts TAS, at the tropopause it's about 573 kts TAS. (First person to bring up KEAS vs. KTAS gets a head slap from Leroy Jethro Gibbs!). Google will provide you with more details, should you wish.

Ya, I better disclaimer this: I also have extensive experience/knowledge of turbojet and piston aircraft operations, but do not own a jet.

I once came moderately close to being part owner of an ex-Czech AF Mig-21F Fishbed C. Fortunately, sanity prevailed (especially since I wouldn't get to fly it) :D

Can you guess what plane I was on when I heard this?:

Obviously one that served lots of re-heated tea and coffee. Or, since this forum deals with vehicles that wouldn't exist without government incentives, the Concorde :D

Survival of the fitness... But, that's why we stagger the launches. There's no requirement to follow any course; just hit the to-be-announced checkpoints.

Tony,

I hope the momentum for this rally is still going.

Also, if anybody is looking at shipping their vehicle from SoCal back to the Seattle area after the rally, please PM me. Perhaps something can be coordinated to get the best possible price on the transportation of our EVs.
