True, except your mythology is wrong. Everypony knows that Rainbow Dash invented the Sonic Rainboom accidently when she was trying to win a race for Fluttershy's honour at Junior Flyer's Camp. The feat was then proven possible to all when she did it *again* at the Greatest Young Flyer competition in Cloudsdale while she was trying to save Rarity and the Wonderbolts from falling to their dooms. It's elementary, my dear ZStrike.
