Reports from an oil rig worker who saw a fire in the sky on the night Malaysia Airlines flight 370 disappeared are being taken seriously, police sources have confirmed. But New Zealander Mike McKay, 55, has lost his job in the ''circus'' that developed after his report to authorities was leaked. Mr McKay had been working on the Songa Mercur oil rig in the South China Sea when he saw an ''orange light'' on an especially clear night. The object was still in one piece and close to where MH370 first dropped off radar between Malaysia and Vietnam on March 8 with 239 people on board. He emailed his employer and Vietnamese authorities about his sighting, but his statement was leaked, which included his full name, email, passport number, and full details of the company operating the rig. In the ensuing media storm, Mr McKay said the Japanese-based petroleum company, Idemitsu, was flooded with emails and he was taken off the rig. He is now unemployed and disappointed his efforts at reporting potentially vital information turned into such a circus. ''I was only trying to privately help,'' he told Fairfax Media during a series of interviews. ''If it was the aeroplane I saw, then it must have been an external fire. How far would an aeroplane stay in the air after such a fire?''
