One thing really scares my wife that is a reassuring sound to me. It is the sound of a jet engine as it starts to reflect a perceptible drop in power as it puts out less energy so a jet airliner can come in for a landing. My wife worries that we are going to crash. I know that the airliner makes the final approach by shutting down the power so that it can make an approach. I love the trip in a plane, but sometime I know we must return to earth and I plan on making those trips in safety.
