In this lecture we will investigate the properties of the environment we fly in: The Atmosphere

Having seen the fundamentals of the standard atmosphere in the previous clip, Mr. Hoekstra will now investigate how to determine the temperature, pressure and density at high altitudes.

In 1960, U.S. Air Force colonel Joseph Kittinger took place in a helium balloon, which brought him up to an altitude of over 31 kilometres. In this clip, Mr. Hoekstra will use the standard atmosphere to find out what the atmospheric conditions were like at that altitude.

Did you notice that in the derivation of the International Standard Atmosphere in the previous clips we made an assumption which we did not check? In this clip Mr. Hoekstra will explain what this assumption was, and what its effects are.
