It's not a push-button or a switch in the cockpit, it's a part of the control laws in the flight control computers. Just like any other computer, to get good output, you have to gave good input. (The old-time computer geeks used to have their own little word for it - GIGO. Garbage In, Garbage Out.) If the computer thinks the aircraft is waaaay nose-low after rotation not because it actually is, but because of a false sensor reading, it's gonna try to bring the nose up to keep the airplane airborne... and it'll keep trying until: A> the computer decides the aircraft is level (regardless of actual aircraft attitude) OR B> the aircraft stalls close to the ground and bellyflops.
It could have gone the other way, too - the computers could have thought the B-2 was nose-high, and kept forcing the nose down through the takeoff roll. The pilots wouldn't have been able to "pull through" the computer's flight control inputs at Vr, and it would've over-ran the runway and become the newest aircraft in the underwater collection off Andersen's runway.
The pilot-centric solution - wire a guarded switch into the throttles/stick grips that overrides the FCC's air-data inputs that determine aircraft attitude, and allows the pilot to fly the aircraft based on his view out the windscreen.
The maintenance-centric solution - rewrite the TO's to include PITOT HEAT/AIR DATA SENSOR HEAT..........ON as a part of the MX daily/preflight inspection.
