Question Re-phrased:

What speed must an object reach, in order for frictional heating to overcome wind chill, and cause a signifigant amount of heating?

Specific Question 1: How fast must a Boeing 737 go, in order for the airplane's skin to heat to 100 degrees celcius? (Assume no structural failure.)

Specific Question 2: How fast must a bullet go to actually achieve an increase in temperature while in flight?
