FIRST TIME IN A PLANE

Jimmy is about to fly for the very first time and he is a nervous wreck.   He is strapped into his seat, when the cockpit door opens.  The pilot enters the passenger section and with the aid of a white stick, tip-taps down the aisle.  Jimmy is mortified and when the pilot reaches him, he stops him and asks "Excuse me are you our pilot" to which the pilot replies "Yes".   "But your blind" says Jimmy.   "Oh don't worry about that" says the pilot.   "Don't worry" says Jimmy "How the hell can you fly this plane, when your blind".   "Easy" says the pilot "I have a co-pilot and he does all the pre-flight checks, taxis the plane down the runway, when we get to 200mph he hands over to me, and I take off"   "OK" says Jimmy "but how do you know exactly when to take off".   The pilot replies "Well being blind God has compensated me by giving me extra sensitive hearing, and when I hear all the passengers scream Fu....g Hell, I pull back the joystick.
