There you go globalti, a study by Danish gastroenterologist, Jacob Rosenberg, shows that not only do we fart more in planes but it is healthy to do so.

….humans fart more up in the air than on the ground. This is because, they say, higher altitude causes the gut to create more sulfuric acid, which in turn causes us to emit proportionally more farts on a flight than the 10 a day we normally let go.
An aspect of the work they produced is their insistence that we don’t hold back. We may be conditioned to be circumspect about where and how we let out our gas go but Rosenberg smells a problem there, saying that to refrain on a flight could impact your health.
“That (holding back) holds significant drawbacks for the individual, such as discomfort and even pain, bloating, dyspepsia and pyrosis (heartburn), just to name but a few resulting abdominal symptoms,” the study said. “Moreover, problems resulting from the required concentration to maintain such control may even result in subsequent stress symptoms.”
The researchers do note, however, that there is a dilemma for those working in the cockpit. “On the one hand, if the pilot restrains a fart, all the drawbacks previously mentioned, including impaired concentration, may affect his abilities to control the plane,” the study said. “On the other hand, if he lets go of the fart, his co-pilot may be affected by its odour, which again reduces safety onboard the flight.”
