I have to second the actual damage to the cause of STEM - as opposed to support. This is a foolhardy effort at a meaningless thing (around the world) the primary purpose of which is to capture publicity. The pilot has to justify it (possibly even to herself) as meaningful so adds the STEM and Gender Flag Waving. I’d have more respect for the effort if she’d just done it for no reason. There is not positive here for either of the “causes” claimed.
That being said, for an 80 hour pilot to attempt this flight VFR - in that aircraft - is nothing short of plain old stupid. Not because she’s female, not because she’s 19; just because it’s bad Aeronautical Decision Making. I consider myself a pretty risk friendly pilot and I’d never have attempted around the world with 80 hours. Heck I wouldn’t feel good about it it 43 years - and many many hours - later.
Success isn’t even an accomplishment in this case. You could stand in the middle of a busy Interstate Highway for 24 hours. You might survive it. But if you do, it’s not an accomplishment; it’s pure dumb luck. Same thing here.
I hope she makes it. I really do.
