A probe has been launched into the mysterious landing of a small aircraft at the Ian Fleming International Airport here in St Mary about 6:15 yesterday morning.

However, it reportedly took-off shortly afterward without any activity, leaving airport workers, including police personnel and private security at the facility baffled.

Speculations were rife yesterday that the pilot may have been surprised by airport workers who had it under close observation from the minute it landed.

Head of the police's Transnational Crimes and Narcotics Division Senior superintendent Warren Clarke told the Observer that allegation that the aircraft was loaded with narcotics has not been substantiated.

He said the division has received a report into the action of the aircraft, which he described as being "strange" and said that the police have commenced their investigation.

"Nothing was taken off or placed on it," SSP Clarke said. Security personnel, he said, had the aircraft under close observation from the minute it landed until it departed.

Vice-president of marketing and commercial at the Airport Authority of Jamaica (AAJ) Mark Williams confirmed that a small aircraft landed at the facility, which is operated by the AAJ.

"No one knows what the plane was carrying or who are the persons or the number of persons on board," Williams said.

"We don't know if it was plane troubles or anything; I understand it was (on the ground) for less than five minutes and before they (security personnel) could get there it took off." When asked specifics about the aircraft, Williams said, "we can't say much now on that because some investigations are currently in place so I wouldn't want to say that at this stage."

He, however, said personnel at the airport became suspicious after it was realised that no activity was seen taking place after the aircraft landed.
