Matt Melis, a longtime NASA engineer, has take to the 'Tube to show off what he calls "the best of the best" imagery from shuttle launches, including high-definition video

Melis has been in the launch analysis game for quite some time. His 45-minute tribute to space shuttle launches is incredibly educational and a fascinating watch for fans of space programs.

You'll get to hear NASA engineers explain every imaginable detail of a shuttle launch as footage from the ground and from the shuttles themselves show what goes into the first phase of a successful space mission. You'll get to see launches for STS-114, STS-117, and STS-124 missions.

In short, if you're really into space stuff, this YouTube video is the director's commentary of your dreams.

"Photographic documentation of a space shuttle launch plays a critical role in the engineering analysis and evaluation process that takes place during each and every mission," Melis writes on the YouTube video page.

"Motion and still images enable shuttle engineers to visually identify off-nominal events and conditions requiring corrective action to ensure mission safety and success... Rendered in the highest definition possible, this production is a tribute to the dozens of men and women of the shuttle imaging team and the 30 years of achievement of the Space Shuttle Program."

Melis has been at the Glenn Research Center in Cleveland, Ohio, for many years. He was part of the ballistics team that analyzed the Columbia launch accident, for example.
