Thanks to the internet, experts are able to share their knowledge with millions of people in a very quick way. Now, a frequent flyer has come forward to share why you should never wear yoga pants or leggings on a flight no matter where you are heading to. The aviation expert is also an aviation journalist named Christine Negroni, who has frequently written about how to fly and what are the best ways to take advantage of time in the air – but her recent tips have been met with a mixed reaction since so many people like being comfortable while in the air.

Negroni has written about air travel for several decades. She is also the expert author of the book The Crash Detectives, which is about air travel in the United States and abroad. In a conversation with The Sun, Negroni explained that you should never get too comfortable on a flight. That means you should skip wearing your yoga pants and never take your shoes off while on an airplane for a very sick reason.

She explained: “You might have to escape through a cabin fire, or there could be a separate fire on the ground once you leave the aircraft. Everyone is wearing yoga pants on planes now, but I avoid all artificial fibers because they are more likely to burn and stick to you if there is a fire.”

You should also not take off your shoes when you are on an airplane. If an emergency suddenly occurs and you are not wearing shoes, you will be subjected to a very painful walk to the emergency exit slide and other safety equipment that is necessary during an evacuation of an airplane.

Negroni said, “If you escape an aircraft, the floor could be very hot or cold, it might be covered in oil or on fire, or in a cornfield. (In other words), you won’t want to be barefoot (in the rare event of an emergency on a flight).”

It has long been confirmed that airplanes do not purposely release waste from passenger aircraft while they are in the middle of the air. This myth has been debunked many times over and is simply not true. Negroni confirmed that was the case.

In addition, Veteran Air Canada Dreamliner captain Doug Morris confirmed that passenger bathrooms on a plane are serviced at the airport. He also said that “most ground stops on long-haul flights and less so for short-hop flights.”

When passengers use the bathroom facility on the plane, the waste is flushed to a holding tank that is at the rear of the plane. Captain Morris is also an author who published the book, This Is Your Captain Speaking (ECW Press). He wrote, “There is an access panel near the rear (no pun intended) of the airplane to allow the holding tanks to be sucked of human sewage.”

Do not wear yoga pants or take off your shoes while on a plane.
