When I was little, my mom told me that once when my great-grandma was flying, she reached out the plane window and grabbed some clouds. She said it felt just like big cotton balls.
I didn't fly until I was in high school, so I couldn't test it out. Even then, I just figured that in my great-grandma's day, plane must have had windows that opened. It seriously wasn't till years later that I thought about it again...after I had learned about air temperature and pressure at those altitudes! Sheesh.
