So it's OK to fly underneath a bridge?
If you drive across any large bridge when the weather is anything less than perfect you'll notice the effect on the car.
Imagine what it might be like when you're flying a microlight, a very vunerable a/c by comparison to, perhaps, a C150.
The pilot clearly couldn't have recovered as quickly and one wonders if he has the mental capacity to pilot a kite, never mind a powered aircraft.
Despite what the Flying Lawnmower, who makes a pathetic attempt to make the CAA the big bad ogre, the pilot was wrong and proved wrong.
