Airplanes today, when they leave the runway, typically take off at a steeper angle into the air than they once did many decades ago. The engines have enough power so they can accelerate at a steep angle without getting more horizontal velocity to try to get the lift. So that's one little thing that has changed over the years. Not only that, the engines are quieter than they ever were.
Is it possible to make something invisible? Neil deGrasse Tyson and comedian Chuck Nice explore transparency, how we measure time on Earth, and how airplanes have changed.
