I was also told that even though they couldn't fly in light aircraft they could fly in airliners, so can they do that due to the pressurisation of the aircraft? And I thought that airliners keep the cabin pressure at a higher altitude say 5000ft which is higher than say what a C152 cruises at (when I fly it anyway), so in that case would the ears be affected due to sudden pressure changes?
Sorry to be a pain.
