Not quite so. There was a sighting by oil rig worker Mike Mackay, on Song Mercur oil rig, who noted at the requisite time an aircraft west of himself in the vicinity of Ca Mau peninsula (circa waypoint BIBAN) on fire for 10 or 15 seconds before the flames went out. He said it continued to fly and did not seem to deviate left [south] or right [north] either coming towards him or going away. He said it was about 70 kilometres distant.
