The Science of the Sonic Rainboom

[Pony.inc 38]

What I'm proposing is that any alicorn or Pegasus could successfully perform a Sonic Rainboom, Rainbow Dash or not. Rainbow Dash was talking about it before doing it herself, so it's obviously been done before her. What do you think?

I don't really understand how a unicorn could perform one, perhaps another pegasus, so yes potentially an alicorn could. However, before this goes any further I'd advise you to watch the sonic Rainboom episode of Cutie Mark Labs, he poses some very good points and his theory makes a lot of sense. As for her speaking about it before she performed one, are you sure she mentioned it before she performed one as a filly? I obviously could be incorrect haha but I don't remember that, she performed one as a very young pony. But also, if most ponys could perform them then she would probably have a diffirnet cutie mark, considering she got hers when she performed the "first" sonic Rainboom.

They often referred to the Rainboom as an old mares tale so its likely that it had been performed before because as we know mares tales are often true

Any alicorn or Pegasus can perform one. They just have to have the speed that breaks the sound barrier. Hence, why it's called a sonic rainboom. A unicorn or earth pony can't because they don't have wings and wings are what make Pegasus faster and more capable of breaking the sound barrier.
