Improved Launch Control System was created in 1979.

Les Motor Fire is to jettison the Les Tower (Launch Escape System) usually after stage 1 separation of the Apollo Space Missions Saturn V Rocket after a successful launch. OR to fire Les Tower's engines to abort and take the Command module to safety from a potential launch disaster.

That was used to test the launch escape system and to verify the performance of the command module parachutes for the Apollo spacecraft from 1963-66 in five different times.

The command module was covered by a white escape system before take-off; that was jettisoned shortly after launch to reveal the silver module.
