oh god...
NO by his definition a cork stright air is NOT possible, you must be spinning to go Corked or off Axis.
Corked and off axis straight airs are impossible by anyones' definition
No one fucking cares if you dont think it's corked, or you have a different definition of what corked is, because everyone already calls it corked, so give it up you're only fueling the stupidest debate i've ever witnessed.
It's just like the term "switch", you can't actually ski switch, you ski FAKIE, but everyone says switch and everyone knows switch means backwards. So nobody wastes their time debating that its actually fakie, I suggest you follow suit.
