Write a first person account of the moon landing as if you were there with Buzz Aldrin.  Keep it under 250 words and make it engaging.
All the system checklists are complete as I sit here, strapped tightly into the Lunar Module. The only thing on my mind is all the millions and millions of people on Earth worrying about us and hoping, praying. We are painfully close to landing on the moon and reaching a milestone that humans have dreamed of for thousands of years.

Buzz turns the last of the switches, and the roar of the descent engine fills the cabin. The tiny craft shakes as we control our fall ever so slowly toward the Sea of Tranquility. We've done these thousands of times in training, tested every possible scenario, and still, I feel so unprepared as we get ready to touch down. The ship shudders violently, testing the limits of its engines and setting off quite a few alarms.

All of a sudden, just like that, complete and total silence. A small part of me still wonders if we have crashed, but then I lift my eyes and see the ancient dusty surface of the moon, framed by a glowing earthrise. We had actually done it. We made it. Adrenaline shakes my hands violently as I attempt to operate the camera. I try to capture everything for all the millions waiting back on Earth. We plant the American flag, and the words humanity has waited untold centuries to speak come out of my mouth, "That's one small step for man, one giant leap for mankind."
