It'll be a busy week in science history. This week sees the 75th anniversary of one of the most talked-about aviation mysteries ever--and that's just the beginning.
This week also commemorates the first transatlantic hot air balloon flight—spearheaded by a certain ambitious Brit whose name you may know. And then there's the story of a famous chemist who developed the first vaccine for a deadly disease--and the remarkable engineering feat that enabled a beloved U.S. president to send Independence Day greetings to U.S. territories around the world.
