The liftoff from the moon was intrinsically a tense time . The ascent stage simply had to work. The engines had to fire, propelling us upward, leaving the descent stage of the LM still sitting on the moon. We had no margin for error, no second chances, no rescue plans if the liftoff failed. There would be no way for Mike up in Columbia to retrieve us. We had no provision for another team to race from Earth to pick us up if the Eagle did not soar. Nor did we have food, water, or oxygen for more than a few hours.
