### Blind Man

Husband and wife are waiting at the bus stop with their nine children. A blind man joins them after a few minutes. When the bus arrives, they find it overloaded and only the wife and the nine kids are able to fit onto the bus.
So the husband and the blind man decide to walk. After a while, the husband gets irritated by the ticking of the stick of the blind man as he taps it on the sidewalk, and says to him, "Why don't you put a piece of rubber at the end of your stick? That ticking sound is driving me crazy."

The blind man replies, "If you would've put a rubber at the end of YOUR stick, we'd be riding the bus ... so shut up."

### Enterprise second free flight test

In 1977, the Shuttle Enterprise successfully made its second of five free flights as part of the Shuttle Approach and Landing Tests, at NASA's Dryden Flight Research Facility, California. As during its first free flight test on 12 Aug 1977, it was launched mounted atop a Boeing 747 carrier, and separated from it in flight. Then it freely glided, on its own, in flight within the Earth's atmosphere. It touched down, landing like an airplane, on a dry lake bed in the Mojave Desert. Designated Orbiter Vehicle OV-101, it was a prototype built only for testing; it was never equipped for space flight.Its first inactive (no crew) captive flight test(18 Feb 1977) without separating from the carrier 747, was followed by five more inert captive flight tests, and three more active captive flight tests with crew aboard.«
