The Laws of Physics and Logic are not a 'new hype' merely because the dead are not here to respond to the gullible.

I therefore repeat two of my questions that have not yet received an answer (with thanks to Gonzo for answering the third one most accurately).

1) Is it or isn't it physically (humanly) possible for a commercial airliner with 121 people on board to pressurise normally on the ground prior to takeoff - ie as engine/APU bleeds are turned on - with the Outflow Valve barely open (14 degrees from closed) instead of FULL OPEN as it should have been if the Pressurisation Mode Selector Switch was in AUTO and the ground-air sensors working normally?

2) Is it or isn't it physically (humanly) possible for a commercial airliner with 121 people on board to take off at a cabin rate of climb of 2,500ft/min, when the normal (bearable) rate of cabin altitude change is 500-700ft/min, and the minimum allowable differential with a/c flight altitude is 1,800ft/min (otherwise AUTO-FAIL)?
