Orbital ATK has a contract to develop the four-segment Space Shuttle Solid Rocket Booster into the five-segment boosters for the Space Launch System.

Hi John! That's some interesting info! I find it very interesting that they are using the L-1011 opposed to any other more current aircraft. But hey, I won't complain;) Hahaha!

These use it because it's a Lockheed product. They have lots of spares kicking around I am sure

I just saw a local TV news story here in central FL. This AC is going to launch a rocket of some type this week off the East Coast of central FL near the Kennedy Space Center. It arrived in the area earlier this month.
