I was exagerating about the guy getting knocked over... even misspelling "hyperbole" doesn't change that.... but the down wash is backed by physics, I'm not making it up... so feel free to bring it. The high angle of attack, which the Spit is at because it's rotated to climb out, will generate additional wash... like this:
Play with the Java App here, it's all animated and shit:

This wash has actually been expoited by the Russians in their ground effect transports:

The down wash compresses the air below the wing, increasing it's efficiency, as long as the plane stays a few meters off the ground.
