Hmm. “flight trail” might actually be better than “contrail”. Can we flip this suggestion instead?
- Condensation trails are water/ice plus impurities from any exhaust particles present.
- Pony flight trails, especially wonderbolt-originated ones, tend to add rather more in the mix. Lightning zags, thunderclouds, or Dashie’s trademark rainbow.
- So whatever high-end pegasi are supposed to be doing up there, it’s more special-effecty than just boring old condensation. Although sometimes artists will do a wingtip contrail for fun/cool factor. If there’s to be an umbrella tag, it needs to be the more vague term not the more specific one.
So maybe instead:
contrail –(implies)-> flight trail
rainbow trail –(implies)-> flight trail
No aliases. All implications.
(Not to be confused with the adorable vapor trail)
