Hanging on the wall is some 36 feet of the front fuselage of a 747; the entire airplane is 231 feet long. You can also climb up several flights of stairs and take a peek into the cockpit. You can see the controls and the hundreds of instruments.
For such an incredibly huge airplane, it's odd that it's so cramped in there--smaller than my cubicle! Seating for the pilot, co-pilot and navigator is really tight. Sitting hour after hour in that tiny cockpit can't be much of a joy ride.
So what's up with that camelback hump on a 747?
