^Ever since when do coaster really have defined meanings?
I mean, back in the day people thought a loop was crazy, and now they're everywhere. Woodies used to not loop. 200' was seen as astronomically high, and gravity was the only way to get through the course.
Flying coasters are meant to simulate FLYING, and I can't think of any better way to do that than to be 500' in the air, like some birds would be. While it may not be practical, it would be the ideal fashion for recreating flight.
There is a distinction between proper and practical, and you clearly didn't make it.
