Why were three Osprey tilt-rotor aircraft circling over Palmers Green during President Trump's visit to the UK last week?
This photograph was taken from the garden of a house in Park Avenue, during a visit from the Ospreys. They came on Thursday evening and again on Friday morning, circling at low altitude five or six times and rattling people's windows. There are reports too of them circling over Crouch End.
Donald Trump's visit took him to the US Ambassador's residence in Regents Park and to Blenheim Palace in Oxfordshire, but not, as far as we know, to Palmers Green. So what were they up to, circling menacingly above our bit of the suburbs?
