Think I'd rather go along with Skyraider's theory, level and slow until it just belly's onto the surface, reducing chances of flipping or catapulting yourself out of the shield due to excessive nose down, but good question, and one we've (hopefully) all at least thought "What if..." at some time or other.
Scary thing is, none of us have a real answer to it, just subjective opinions. Maybe worth writing to Flyer for the defininitive.
