Aviation Expert Speaks on Turbulence in Montana Skies

Posted: Updated:

Dan Hargrove, Director of the aviation program at Rocky Mountain College says several things can lead to unexpected turbulence in eastern Montana.

"There's different things that can cause turbulence. A big common one in this part of the country is what's called Mountain Wave Turbulence. The air comes over the Rocky Mountains and once it gets over the flat country it tumbles and that often is pretty significant turbulence. Another is something called Clear Air Turbulence and that, just like it sounds, is out in the middle of nowhere for no particular reason there's just a small pocket of unstable air that may be completely unforecasted and unannounced."

Hargrove was an Air Force pilot for 21 years and commanded the crews that fly the President, Vice President, and members of the President's cabinet at Andrews Air Force base in Washington, D.C.
