Does space shuttle have ejection seats?
The first two shuttles, Enterprise and Columbia, were built with ejection seats. It was only these two that were planned to be flown with a crew of two. But STS-5 was the first mission to have a crew of more than two, and the commander decided that flying with the ejection seats disabled was the more ethical option.
Why did NASA stop using the MMU?

Did challenger have an escape system?
In an emergency, crew members could open the side hatch, deploy the pole, attach to a lanyard, and slide out along the pole to parachute away from the orbiter. NASA added crew escape systems to the Space Shuttle orbiters after the 1986 Challenger tragedy.

How are the engines on a Space Shuttle shut down?
The three Space Shuttle main engines (SSMEs) were ignited roughly 6.6 seconds before liftoff, and computers monitored their performance as they increased thrust. If an anomaly was detected, the engines would be shut down automatically and the countdown terminated before ignition of the solid rocket boosters (SRBs) at T = 0 seconds.
