I'm not a pilot, but was on a flight from Gibraltar to Luton in the late '80s with a bunch of school cadets. At the start of the flight, imagine a bunch of cocky teenagers having a laugh; this lasted for most of the flight 'till we started the final approach through heavy snow and turbulence, until a nervous silence gripped the cabin for the last few miles. As we touched down there was some considerable, relieved applause! Can't remember if I joined in or not....
