This month, I have to confess to you all that I am a very poorly traveled person. I didn’t take my first flight until I was twenty-five, and since then I’ve only flown a few more times. Part of this is due to economy, and part of this is because for about a decade my husband refused to fly. When his brother got married in Michigan, he had to leave on a train four days before my daughter and I left to enjoy our flight. But I love flying! As the plane launches itself off the tarmac, I like to think about all the scientists and inventors whose work went into solving the mystery of flight.
