Space Cowboys (2000)
"Negative Return" means that the Shuttle is beyond the point of being able to return to to the Kennedy Space Center and the Shuttle Landing Facility.
"Two Engines TAL" means that the Orbiter can reach the primary emergency Trans-Atlantic Landing (TAL) site in Merona, Spain even if one of its three Main Engines fails.
"Press to ATO" means that if one engine fails, the crew will make every effort to Abort-To-Orbit instead of landing at the secondary emergency landing site in Zaragoza, Spain. After ATO, it may still be possible to perform the mission as planned if the orbit is close enough to nominal.
