I watched a pax jet approach GIB and end up with an instant 70 degrees of bank due to turbulence. It diverted to Malaga, but the Spanish Authorities refused to allow the pax to disembark. I spoke to the captain [an old mate] later in the day. Apparently, the whole cabin stank, because a lot of pax had been airsick all over the place, so the captain led the pax off the aircraft, elbowing the Spanish police out of the way in the process!
He had the cabin cleaned and recovered to GIB later when the SW gale abated.
