Wake up call

A man and his wife were having some problems and were giving each other the silent treatment. The next week, the man realized that he'd need his wife to wake him at 5 a.m. for an early flight.

Not wanting to be the first to break the silence, he finally wrote on a piece of paper: "Please wake me at 5 a.m."

The next morning the man woke up, only to discover it was 9 a.m. and he'd missed his flight.

Saturn rocket

In 1966, a Saturn I-B rocket, an unmanned Apollo test flight, the first Apollo orbital mission, was launched at Cape Kennedy and made 4 orbits at an altitude of about 113 miles (180-km). The AS-203 mission successfully evaluated the performance of the S-IVB instrument unit stage under orbital conditions and to obtain flight information on venting and chill-down systems, fluid dynamics and heat transfer of propellant tanks; attitude and thermal control system, launch vehicle guidance, and checkout in orbit. The Saturn rocket was designed for lofting humans to the moon, requiring a rocket larger and more powerful than any built before or since. It combined five F-1 rocket engines to yield more than 7.5 million pounds of thrust.
