BBC news just now,
When asked to change height by ATC, investigation shows he dialed in mutiple heights from 100 ft 49,000 ft, but did not activate them
Ie F24 would not show it.
Unfortunatley I could hear but not see the TV, and they appeared to show a graphic of "him" turning a dial" sure it makes sense to pilots.
The captain was not in the cockpit at the time, and they clearly stated no one on board would have sensed any change of height ( there wasn't one), he practiced turning a dial!!
possibly as per post above by Hoppy to see ATC reaction.
