Huge US military aircraft hover over London park as Trump visit gets underway

This is the sinister moment two huge US military aircraft hover over Regent's Park in London as the build-up to Donald Trump's visit gathers pace.

Park-goers enjoying the sunshine were interrupted by the V22 Osprey tiltrotor military aircraft, which can take off and land vertically.

They whipped up grass and litter as they skimmed the treetops on Monday afternoon.
