Exploring exoplanets with NASA's new telescope; New book chronicles the fall Boeing

The James Webb Space Telescope — the most powerful of its kind — will launch into space on Dec. 22. Astronomer Laura Kreidberg talks about what she hopes to learn about the atmosphere and weather of exoplanets. And, aviation reporter Peter Robison talks about his new book "Flying Blind: The 737 Max Tragedy and the Fall of Boeing," a deep dive into what caused two fatal crashes of Boeing planes.
