An EgyptAir flight that crashed in the Mediterranean did not swerve and change direction before disappearing.
The Airbus A320 was en route from Paris to Cairo with 66 people aboard when it vanished from radar early on Thursday.
Greece's defence minister said the plane turned 90 degrees left and then did a 360-degree turn towards the right before plummeting.
But senior Egyptian aviation official Ehab Azmy said there was no unusual movement.
Azmy told Associated Press the plane had been flying at its normal height of 37,000 feet before dropping off the radar.
Some debris has since been found.
