Rainbow Dash has her friends to help her out and imrprove. it’s safe to assume that LD doesn’t.
It would have been nice if RD wasn’t the only one that learned a moral lesson. It’s not only the main characters that can learn lessons, but other side characters. RD could have tried to offer her hoof to LD and the episode could have ended cutly with them zooming up into the sky then credits roll in. :3

Wow. Once again I am shocked at how stupid the LD haters are. Seriously. The entire run of events could have been stopped cold if Spitfire did her job properly instead of actively encouraging LD to do reckless shit by rewarding her for doing it. All she had to do was slap LD down for her attitude and impress upon her that it was a bad attitude to have back around the Dizzitron thing or when her leadership got dash visibly injured. You know, like real trainers should do when training people with potentially dangerous attitudes.

It’s not like Spitfire is the one who is responsible for ensuring her cadets are properly trained in how to conduct themselves and behave in a safe and responsible manner after a-… oh, wait, no. As the person in charge she is responsible for ensuring that.

Further people seem to act like LD deliberately set off that Tornado while there were civvies in the area… uh… when there weren’t. Twi and co showed up after it was out of control. When LD began the tornado it was, though unnecessary, theoretically ‘safe’ to do so. No-one was in the way, etc, it going out of control was something she couldn’t predict when she started it after all - reckless though she is I doubt she’s stupid enough to do something she knows she can’t do to impress the wonderbolts.

And lastly… as to her being unconcerned about everyones safety… I can only tell you to go back to Sonic Rainboom and watch how even Fluttershy clearly cares more about the fact that RD did a rainboom than she is concerned about Rarity’s health after her near death. Ponies not giving a shit about ponies provided everyone lives is not something limited to LD.

Oh also you seemed perfectly okay with NEAR MURDER. Good job, you deserved the punishment.

As everyone else has said, one mistake yes, but a mistake that you caused which risked not only the lives of your fellow Wonderbolts-to-be but also those of five innocent civilians.

Seriously? What the flying feather?

Lightning Dust made her bed. Now she can sleep in it.
