Radio Receiver Used in the Piccards' Stratospheric Balloon Ascension, 1934

In October 1934, Jean and Jeannette Piccard set a new altitude record, ascending 10.9 miles in a metal gondola carried by a hydrogen balloon. Jeannette -- the first American woman licensed as a balloonist -- piloted, while Jean gathered scientific data. On this historic flight, Jeannette became the first woman to reach the stratosphere.

Ford Motor Company's Mustang, introduced in 1964, was such a success that other car makers soon copied it, including Ford itself. Mercury's Cougar was based on the Mustang, but with more upscale styling and interior appointments that made it something of a "poor man's Jaguar." This Cougar has the rare XR7-G package with a hood scoop, sun roof, and other special trim features.

During his polar expeditions, Richard E. Byrd relied on navigational instruments not much changed in 200 years. Byrd's sextant measured the angle between an astronomical object -- the Sun or a star -- and the horizon. Based on the time of day it was measured, this angle was used to determine Byrd's position on a navigational chart.
