There were red faces at Tokyo MX on Wednesday when a drone being flown during a news shoot ended up in the grounds of the British Embassy in Tokyo, the TV station admitted Friday.

Although hardly an incursion into British airspace, the incident came hours after a similar drone apparently carrying a radioactive payload was noticed on the roof of the Prime Minister's Official Residence.

Tokyo MX, or Tokyo Metropolitan Television Broadcasting Corp., said news staff had been flying the drone from the company's parking lot while filming a report about drone capabilities when they lost control, allowing the aircraft to drift onto the grounds of the nearby British Embassy in Chiyoda Ward.
