We've all felt that sweet relief of finally landing back on firm ground after a bumpy flight.
But if you've ever felt compelled to applaud the pilot for landing safely, think again.
Pilots actually hate it when passengers clap. According to a Q&A on internet forum Quora, Scott Kinder, who identified himself as a 737 captain of a major US airline, said it is ignorant.
"Don't even think about it. Passengers really have no idea what's going on upfront with the landing, so how do they know what to clap for and what not to clap for?" Mr Kinder said.
"If a pilot floats a landing and lands half way down the runway, that's horrible and dangerous. But if it's smooth, he gets claps from the back?
