I'm sure that any time the crew or the ground don't like the numbers they are seeing, they'd push the button. As I'm sure you're aware, they have cue-cards onboard which tell them what they should be seeing during ascent and landing. If there was a serious deviation, and the BFS numbers were correct - the button gets pushed.<p>I have to ask, however, how would the dolilu get messed up? When the crew is given the updated values they read them back, and enter them, then verify that they are correct. It would take a <i>really</i> convoluted set of screw-ups for the wrong values to be entered.<p>Oh, btw, "Now take you meds and try using some whitespace."</p></p>
