Puppy ears & hearing - need to fly 4-week-old pups !

I'm not an expert on puppy's hearing, but I have flown in an older, small, single engine plane. The humans had to wear headphones, for hearing protection and communication. It was so loud that you couldn't scream loud enough to be heard. Wind blasts would really throw the plane around. Every time I went up, I couldn't wait to see that landing strip! I'm sure puppies get transported in this fashion all the time, and it is for the best-but I just wanted to give my experiences. Good Luck!
