Yes she’s kind of a play on Amelia Earheart. Since she’s an RP character I wasn’t bothering with subtlety. The idea is that she was the captain and pilot of an airship set aside to give foreign aid.
She’s very self confident though in that snooty upper crust way, not in Dash’s tomboy way. But Rainbow got her live fast, die young, devil may care attitude from mama. Her looks and ace flying talent comes from her father’s side. Air Heart probably smokes a lot so eventually her aerial edge would be lost due to messed up lungs. But she can maneuver an airship like it’s nopony’s business.
A while ago it was my idea that Dash’s mom died during child birth. But now I have an option 2, that she seemingly vanishes off the face of the planet just like Earheart. The world beyond Equestria is a mysterious and perilous place.
