I don't know enough about it but if Gravity probe B (GP-B) proves certain predictions concerning General Relativity were a figment of Einstein's fertile imagination, then...
...it would probably lose the great man some cred, put a lot of clever people out of a job and make some people's life work irrelevant but what does it mean for the average man in the street and what are some of the far reaching implications stated in the following excerpt from the GP-B website???
What is GP-B?
Gravity Probe B is the relativity gyroscope experiment being developed by NASA and Stanford University to test two extraordinary, unverified predictions of Albert Einstein's general theory of relativity.
The experiment will check, very precisely, tiny changes in the direction of spin of four gyroscopes contained in an Earth satellite orbiting at 400-mile altitude directly over the poles. So free are the gyroscopes from disturbance that they will provide an almost perfect space-time reference system. They will measure how space and time are warped by the presence of the Earth, and, more profoundly, how the Earth's rotation drags space-time around with it. These effects, though small for the Earth, have far-reaching implications for the nature of matter and the structure of the Universe.
(quoted from Gravity Probe B: Testing Einstein's Universe)

Re: Hint:
free fall as in one of those planes that take a sudden dive so that the people in it and the observer appear to counter the effect of gravity so GP-b with it's suspended gyro's in effect has the characteristics of zero gravity and thus is able to make measurements of the warp effects on space time by a mass object without factoring in the effects of gravity...
...kinda like taking measurements in a plane dive that keeps diving
I am so out of my league here but you should see me when i care. I look exactly the same, just words on a screen
