Emiliano Sala search called off for the day as authorities find no trace of missing plane. The search began in the English Channel around the island on Tuesday and went on for two days before getting called off on Thursday. Guernsey Police tweeted: "After an intensive search using multiple aircraft and one lifeboat over the last nine hours, we have found no trace of the missing plane."
The aircraft, passenger and crew are therefore missing until physical evidence emerges to otherwise determine their exact whereabouts. Whilst the known facts, weather conditions, aircraft type, passenger, pilot etc. have been debated across this thread, there are historic references to unexplained sightings of 'unidentified flying objects' in the Channel Islands area filed by commercial pilots, in particular in and around the last known position of N264DB before vanishing from Jersey radar. If you're interested in reading the reports etc. (which appear to be credible) search Wikipedia 'Alderney UFO sighting'.
