Sonic Rainboom

Sonic Rainboom is the sixteenth episode of My Little Pony Friendship is Magic, season one. The episode is named after Rainbow Dash's signature aerial acrobatics maneuver, the sonic rainboom. In this episode, Rainbow Dash enters the Best Young Flyer competition, hoping to win a day with her idols, The Wonderbolts. However, she is worried that she will not be able to perfect her moves for it. The episode's title is a portmanteau of "sonic boom" and "rain/rainbow".

Production and airing
This is one of the few times that the Treehouse channel does not mute the word "loser" in its airings of the episodes. Rainbow Dash says "The Wonderbolts will never let a loser like me join!" Two sound clips are also recycled from Friendship is Magic, part 1. Rarity's laugh is the same as her shocked scream when she noticed Twilight's unkempt hair. Fluttershy's inhale is Pinkie Pie's gasp (also reused for the crowd in that episode when Celestia is revealed to be missing) played backwards.

Preparing for the competition
The episode opens with Rainbow Dash coaching Fluttershy on the elements of a good cheer, but Fluttershy only manages a very soft "yay" even after several tries. Dash then practices her Best Young Flyer competition routine, which culminates in the "sonic rainboom", where she accelerates towards the ground creating a trailing cone around her, though it's an inaccurate depiction of the vapor cone of fighter jets. However, the cone suddenly rebounds her and she is catapulted right into Twilight Sparkle's library, tossing the place up just after Twilight thanks her friends for cleaning up the place.

Rainbow Dash tells the rest of the ponies about the competition, including the grand prize: a contest's crown and a full day with The Wonderbolts. Pinkie Pie tells Twilight what a sonic rainboom is, although she adds that she has never actually seen one (which is not true, since as a filly she came into direct contact with it, leading to both the style of her mane and tail, and getting her cutie mark). However, Pinkie says that Dash is said to be the only pony ever to pull it off. Dash takes off to rest before heading to Cloudsdale. The name Cloudsdale is curious. "Dale," when associated with places, is an old word for a valley. It is also a pun on the Clydesdale breed of horse. Before Fluttershy leaves to work on her cheering, she tells the others her concerns:

"She's practiced that move a hundred times and she's never even come close to doing it. I don't know if I can cheer loud enough to help her..."

- Fluttershy

Recognizing Dash's recent attitude as a form of stage fright, Rarity convinces Twilight to find a spell that can take them to Cloudsdale to join Fluttershy in cheering their friend on. Pinkie Pie instantly finds the specific page with a flight spell, on account of it landing on her face when Rainbow Dash crashed. The spell would allow any Earth or unicorn pony to have wings for the next three days, but Twilight notes that it is an extremely difficult spell, and asks for a test subject.

Rarity volunteers after a moment's pause. Despite the difficulty, the spell is a success, granting her large, translucent butterfly-like wings. However, Twilight could only complete the spell once due to the difficulty. The remaining ponies are still able to visit Cloudsdale, thanks to an easier spell that allows non-Pegasi to walk on clouds for a limited time.

Cloudsdale
Upon the two Pegasi landing back in their hometown, Rainbow Dash runs into a trio of male Pegasi who know her from childhood. They proceed to make fun of her, calling her "Rainbow Crash" and claiming she will never pull off the sonic rainboom, which they dismiss as "an old mare's tale." Fluttershy, trying to be more assertive, defends Dash, saying that she will make the sonic rainboom happen and challenges them to show up at the Cloudiseum, Cloudsdale's stadium, to see for themselves. Dash becomes nervous, even more so when Fluttershy inadvertently reminds her that she will have an entire audience of super-critical sports fans to impress with a move she never pulled off in practice when the contest actually starts. She panics until she and Fluttershy see Rarity with her temporary wings. The appearance of her wings might be a reference to the 1980s first-generation Flutter Ponies toys, whose sheer butterfly wings were notoriously fragile. Twilight, Pinkie, and Applejack soon arrive in their hot-air balloon and explain Twilight's spells to the Pegasi. Flattered by her friends' support, she and Fluttershy decide to show them around the city.

The first stop is the snowflake factory, but they are forced to abruptly leave when the fluttering of Rarity's wings blows the snowflakes into disarray. Next is the rainbow pools, where rainbows are mixed. Pinkie curiously tastes the concentration, learning the hard way that it is too spicy, as Dash notes that "rainbows aren't really known for their flavor." Throughout the tour, Dash sees Rarity causing some commotion as the city's residents gawk at and compliment her new wings. Dash's pre-competition anxiety is heightened by the new concern about her own pair of wings being too boring. The final blow to her dignity comes in the cloud-making department, when some of the spectators recommend that Rarity take part in the competition. Rarity, basking in the radiance of her fame, quickly accepts. A completely demoralized Dash states that she will never win the contest now.

The stadium
At the stadium, the competition begins. Princess Celestia is in attendance along with The Wonderbolts, three of whom are the special judges of the event. Overcome with fear, Dash avoids going out to fly by switching the number on her flank, originally two, making her the second flier, with other competitors' numbers. Meanwhile, Rarity is busy grooming herself in preparation for her flight. When her turn comes, Rarity informs the competition organizer that she is not ready, allowing several other Pegasi to go before her. Watching from the stands, Twilight and the others are impressed by the competition so far, but are eager to see their friends perform. The order of the contestants are as follows:
 * 1 – "Dizzy Twister"
 * 2 – Rainbow Dash, moved to #5 then to #6 and then to #15
 * 3 – "Cloud Kicker"
 * 4 – Rarity, delayed & competed with Rainbow Dash
 * 5 – Time Turner, moved to #2
 * 6 – "Parasol", moved to #5
 * 7 – "Leeroy Wingkins", who exclaims "LET'S DO THIS!"
 * 8 – "Lucky"
 * ?? – "Medley", tag obscured, possibly #10
 * 10 – unknown, but "she just looked like such a nice pony", according to Fluttershy
 * 12 – "Caramel"
 * 15 – Derpy, 15 and presumably moved to #6

Rainbow Dash and Rarity are up
The contest is about to end, and Rainbow Dash, now wearing number 15, and Rarity are the only competitors left in the waiting room. The organizer informs the two ponies that, because there is only enough time left for one performance, the pair must go out together. Rarity steps out of her dressing room in an extravagant ensemble and makeup. She wishes Dash good luck, unaware of her friend's extreme anxiety, and notifies her that she changed the music to better suit her performance, which is a rearrangement of the waltz from Tchaikovsky's Swan Lake. Dash tries to concentrate on her own routine, but still stumbles from the start of her performance. She bumps into one of the cloud columns during her first phase, and loses control of one of the clouds during her second phase, almost hitting the Princess. Knowing that she needs to pull off the sonic rainboom to have any hope of winning, Dash begins her preparatory ascent. Rarity, meanwhile, decides to end her performance by flying in front of the sun so her wings will shine down onto the audience.

The grand finale
Rarity's grand finale is a success, as she flies up to the sun and beams her wings over the stadium. However, as Twilight warned her earlier, Rarity's temporary wings are too delicate to survive the physical and elemental strain of the flight due to the wings' flimsiness. This echoes the story of Icarus from Greek mythology. The sun burns the gossamer wings into ash, and Rarity plummets. Three Wonderbolts (Spitfire, Soarin', and Misty Fly) immediately dive to rescue her, but are knocked out by Rarity's flailing limbs.

Rainbow Dash notices what is happening and quickly dives down to catch up with them. Pushing the limits of her acceleration, Dash finally breaks the sound barrier, managing to save all four from hitting the ground and unleashing the beautiful sonic rainboom for Cloudsdale's audience to see. In this successful attempt, she leads with two hooves, in contrast to the previous attempt where she lead with one hoof. Twilight, Pinkie and Applejack can only gape, but Fluttershy explodes with excitement, screaming and cheering as Rainbow Dash and the four safely return to the stadium.

Epilogue
In recognition of Rainbow's bravery and flying skill, Celestia names her the winner of the competition. Most importantly, Dash earns her prize of hanging with The Wonderbolts, who thank her for saving their lives. The three male Pegasi who repeatedly mocked her prior to the contest apologize and ask if she wants to hang out with them, to which she replies that she has plans with the flying troupe.

Rarity, in the safety of the balloon's basket, apologizes to everyone for getting caught up in the excitement of showing off her wings and overshadowing Rainbow Dash in the process. She reports to Celestia that she has learned to be there for her friends, while keeping her hooves on the ground, literally and figuratively.

In Sleepless in Ponyville, Rainbow Dash tells the other ponies present to prepare to hear "the best story [they've] ever heard"; Scootaloo asks if the story is about the events in this episode, to which Rarity flushes with embarassment.
