Touchdown of Apollo 11 had many unknowns for the first lunar landing. Dodging the craters and boulders on the moon to land on a firm surface without totally running out of fuel for the return to Earth was a breathtaking experience. The author recounts his press briefing to the world's journalists prior to the 1969 launch at Cape Kennedy, followed by how he became an aerospace engineer. Building a suit to protect the astronauts from the unknowns encountered in the extremes of space and on the lunar surface was an ongoing challenge. Details such as the effects of cosmic rays, thermal extremes and micro-meteoroids on the human body were addressed as they were discovered over the eight-year period following JFK's challenge. Key engineering changes to meet the new requirements for the space suit that had to be tested and implemented before each mission are described. Applications of the new technologies, materials and processes developed in the space programs adapted to industrial and consumer products are also delineated.

For years, people in “Tornado Alley” were the ones who had to worry most about tornadoes occurring near their homes. However, as climate change occurs, tornadoes have become more common around the United States. Tornado prediction and tracking has gotten increasingly better, too. Readers learn how tornadoes happen, how they are measured, and what to do if a tornado watch or warning is issued. Real-life stories of tornado devastation, such as those that occurred in Joplin, Mississippi, in 2011, emphasize how serious this weather event can be. Full-color photographs and sidebars offer additional perspectives about tornado chasing, destruction, and preparation.
