From Quiz Twelve Months a Year
Answer:
space shuttle explosion
In late 1985, NASA designed a new program called the Teacher in Space Program in an effort to get children interested in space travel. Out of 11,000 people, Christa McAuliffe, a high school teacher from Concorde, New Hampshire, was chosen to take part in the program. Her mission would be to conduct lessons from space aboard the shuttle Challenger. After many delays, Challenger finally lifted off on 28th January 1986. Seventy-three seconds later, in front of a horrified crowd which included the crews' families, Challenger suddenly exploded. All on board died. The cause of the disaster was a faulty seal on the right Solid Rocket Booster.
