It was approximately seven o’clock in the evening when Riccardo Marano approached Caselle airport in his Piper Navajo. As he was about to land, the control tower radioed information of an unidentified flying object some 1,200 feet (365 metres) over the runway. Marano aborted the landing and flew towards the object, but it zigzagged away in a non-ballistic motion quite beyond the capabilities of any aircraft. Given the distance it covered, Marano estimated it to be moving at approximately 3,100 miles (5,000 km) per hour.
There was no lack of corroboration for the sighting; it was detected on the airport radar, on military radar, and visually sighted by two other pilots and several civilians at the airport.
