Best Answer

On launch day, astronauts usually wake up four hours before launch. They enjoy a pre-launch breakfast, then get suited up in their orange Advanced Crew Escape Suit (ACES) space suits. After they are suited up and ready to go, the astronauts walk out from the Operations at Checkout Building at the Kennedy Space Center and climb into the Astrovan, which takes them to the launch pad. At the pad, the astronauts ride an elevator to the 195-foot level, where the close-out crew helps each astronaut board and strap into the shuttle. After that, the astronauts wait about two and a half hours until launch.

You might get receive an order to "Hold short of runway" before takeoff, but not during takeoff.

Once you're "cleared for takeoff" you can taxi onto the runway and takeoff


What do you do when you have engine failure during takeoff?

Every aircraft have their own procedure . mostly in airlines when u r in takeoff run u will calculate v speeds and depends on that the procedure will vary . for example you got one engine failure during takeoff run and its before V1 speed you can abort the takeoff and if you already crossed V1 speed you must takeoff and then you can follow the A/C engine failure procedure to land back asap using single engine.
