 And it's because pantyhose, polyester, they were all melting. And from that day on, they said, you should only wear cotton when flying. Because these materials, like the shirt that I'm wearing or Beau's wearing, will melt due to the heat if you're in a tragic situation. So back then, people wore pantyhose and they wore polyester. And they would say, don't wear, only wear cotton. So to this day, when I fly, I only wear cotton because of that.
