Sunday July 19, 8pm HISTORY CHANNEL---Zero Hour

See me keep cool with nerves of steel as disaster looms in 'Zero Hour - 'Falling Star Columbia' on Sunday, July 19 at 8 PM on History TV.

As Leroy Cain, Mission Control Flight Director, and last person in contact with the crew aboard the Space Shuttle Columbia, Zero Hour counts down the final hour of one of the most catastrophic events in the history of space aviation when that very space shuttle, the most advanced vehicle ever built, disintegrates in a fireball in the sky over Texas.

Tragic yet edutaining at the same time.
