This means that it was the fast transition between the climb and descent attributable to the turbulence – and never the precise change in altitude itself, which was comparatively minor – that brought about pandemonium within the cabin.

The Flightradar24 knowledge confirmed that the Boeing 777 first attained a climb fee of 1,664 toes per minute (fpm) – or 507m per minute, double the peak of 52-storey Capital Tower – earlier than descending at 1,536fpm six seconds later.
