Interesting story format! Hope you keep writing more MLP:FIM fanfics!

That was badass. The pacing and descriptions were all spot-on. Got my blood racing. Loved it!
Unfortunately I don't have any little tidbit criticisms to provide for you as you always do for me, but I figure you probably wouldn't have heeded them anyway. ;)

Very good analysis of the Sonic Rainboom's physics. Great job with RD's thoughts.

Keep the good writing.

That was fantastic. I love the incredable detail you went into with Rainbow's thoughts, not only were they believable but I can totally see her thinking all that during the scene. One of the best parts had to be the science you brought up, something that totally didn't enter my mind. Over all, this was an amazing read! Great job.

Nice combination of aerodynamics and detailed mental activity.

I like this. It really does sound like it was written in Rainbow Dash's voice. The fight to break the sound barrier was really exciting, even when we've all seen the episode. Well done!

Very nice! Welcome to the fandom! Interesting analysis of pegasi anatomy and a nice look into the rainbow covered brain of our favorite pegasus. This is at least 20% more awesome than average! Great work!

I positively LOVE this logically thought out reconstruction of the episode taking a lot more into account than they have time to think about in a cartoon and STILL making it work.
