In all, these airmen flew 1,578 missions, destroyed 261 enemy aircraft, and were awarded how many medals?

In 1845, Stephen Perry, a British inventor and businessman, patented what is now a staple office supply—the rubber band. While their intended function is to hold items together, rubber bands have been used in a number of other capacities; they can be wrapped around one another to form a bouncy ball or used as “ammunition” in rubber band guns. Though many modern rubber products are commonly made with synthetic rubber, rubber bands are still primarily manufactured using natural rubber. Why? 
In 1985, members of the US National Security Council (NSC) secretly authorized weapons sales to Iran in an attempt to secure the release of US hostages held in Lebanon by pro-Iranian militias.

Poindexter were indicted and convicted of various offenses. Why were their convictions later overturned?
