US Military V-22 Osprey aircraft fly over London as part of a security drill days before president Donald Trump visits the UK.
The intimidating planes flew over parts of central London as part of the £30m security operation to welcome the president.
Footage shows the twin-rotor aircraft hovering over London with iconic landmarks on show, such as the BT Tower and the Shard.
The president will arrive in London on Thursday and is believed to be spending minimal time in London before heading to Scotland.
