NASA scientists aren't the only ones who can play with rockets! Once a year, the most fearless and hardcore of all rocket builders from around the country come together at LDRS and go head-to-head to see who can build the meanest, baddest most powerful rocket around. For five days, countless rockets burst into the sky with a billow of smoke, racing thousands of feet straight up in a matter of seconds. In fact, the FAA has no choice but to divert all air traffic around the entire event!
