Airplanes Refresh Cabin Air 20 Times an Hour

I was on an airplane a couple days ago and the person in front of me was coughing a lot, they sounded really sick.

I was just starting my vacation and the last thing I wanted was to get sick. So, I couldn’t help thinking about being trapped on the plane for the next four hours, breathing the same air as them.

He instructed the crew to return to their seats and buckle up; before they made it to their seats, we hit a low pressure air pocket and the plane took a sudden drop.

It was just like a roller coaster making its towering first drop. We were in free fall for what felt like a really long time, but was probably only a couple of seconds. A few people flew out of their seats and hit their heads on the overhead bins, the crew was in the isle and did the same. Drinks, books, purses and other personal articles were thrown around the cabin, making a huge mess. (more…)
