This does sound like a really cool coaster. I have only been on one flying coaster - Tatsu - and it was awesome - one of the best. Manta sounds like a really cool ride with a lot of work also being put into the theming - thus creating a great "experience". I must get to Orlando one day - 2...
Sounds good to me. Seems like they are going to build it very quickly if they think it may be up by September 09 - hopefully they don't rush it and it ends up looking dodgy.
