On Earth-2A, a scientist used his magnetic telescope to bring Falcon to Earth to study it, and then send it back into outer space, but since the Metropolis Police Department felt that the experiment was too dangerous, they sabotaged the machine's dynamo, but it was done when the experiment already started, so because of this, the professor could not create a controlled descent, and the pull of gravity would cause the comet to fall to Earth. Luckily, Superman arrived to save the day, fixing the machine in time to get it sent back into space.
