A senior Trump administration official said a decoy Air Force One flight carrying no president was escorted by US fighter jets on its journey to the United Kingdom. The reported security measure was intended to protect President Donald Trump’s real travel plans amid what was described as a credible threat from Iran.

Reports said Trump secretly left a July NATO summit aboard a smaller US military aircraft, using an airport catering truck as cover while an older Air Force One aircraft acted as a decoy. The fighter-jet escort reportedly accompanied the decoy aircraft to the UK, illustrating the extensive precautions taken around presidential travel during heightened security concerns.
