In spite of Twilight Sparkle recently receiving wings with her "Ascension" she remains apprehensive at best about her new appendages and refuses to fly. Luckily one Rainbow-maned Pegasus has a lot (and i mean A LOT) of experience flying. She knows she can get Twilight to fly if she just show her how amazing it can be...and spending time with her favorite egghead wouldn't hurt either.
I'll be highly surprised if no one's done this before but here's my take on it.
