Hi Guys,
Is it thought to be correct as reported that the secondary radar returns from the flight were suddenly lost and (at the same time?) the primary radar showed the aircraft in an unexpected turn? The aircraft entered a steep dive which looks like it continued into the sea - the parts found remote from the impact area might have come off on the way down. There was no distress call received? and up until the loss of SSR, the flight had been progressing normally?
