Can you imagine someone 2 millennia from now finding Amelia Earhart? Will they even know who she was? Will they be able to figure out the purpose of the machinery around her, or will they be so far removed from the age of mechanical, piloted flight that they will have no context to understand what it is? Will there be enough left to determine that it <i>was</i> an airplane? Will they even believe we had the power of flight, before we ever had computers, scoffing, "how could they have flown? Such primitive people could never have managed all of the equations necessary for flight in their heads in real time."
