Maybe he was making an approach to land, then, without getting within 500' of any person, etc.., decided that in the interest of safety he should divert. So really this pilot has shown a great sense of airmanship and should commended.
Bloody newspapers, love to make a mountain out of a molehill. Did anyone actually see this "swooping amphibian" making "white knuckle rides" and the "rogue pilot"?.....BTW have Portsmouth got a Police "plane" or do you think they mean "H-e-l-i-c-o-p-t-e-r" ? [I can just see it now, the Police in hot persuit in their aeroplane with blue lights flashing..........dumb-ass springs to mind
