… The average person passes gas about 10 times per day.
… The smell of women’s gas is significantly worse than men’s.
… Flatulence on airplanes is particularly insidious because approximately 50 percent of cabin air is recirculated, which recycles the odor.
… People produce more gas at cruising altitudes than at sea level because of changes in air pressure.
… A typical fabric airplane seat cushion can absorb about half of the odor expelled. However, the leather seats common in first and business class sections tend to repel the gas, creating a “less comfortable experience.”
… People with a weak pelvic floor are less able pass gas silently, and should consider “decoys” to distract from the noise such as “coughing, sneezing, verbal outbreaks or spontaneous applause.”
… Smoking bans on airlines increase the risk of “nasally detecting even small amounts of intestinal gases.”
… Flatulence in the cockpit can pose a real flight threat: Holding in gas can decrease concentration and “affect [a pilot's] abilities to control the airplane.” On the other hand, “letting go” of the gas could negatively affect his copilot, “which again reduces safety.”
