And the most peculiar thing is that it's 10,000 feet MSL (above mean sea level), not 10,000 above the ground. When operating in and out of places such as DEN you have only half the distance and time to get there. And coming out of LPB, where the airport elevation is well over 10,000 MSL, you're out of the sterile zone at wheels up.
