Fumbling With His Keys

One night a police officer was staking out a particularly rowdy bar for possible DUI violations.

At closing time, he saw a fellow tumble out of the bar, trip on the curb, and try his keys in five different cars before he found his.

Then he sat in the front seat fumbling around with his keys for several minutes. Everyone else left the bar and drove off.

Finally he started his engine and began to pull away. The police officer was waiting for him. He stopped the driver, read him his rights and administered the Breathalyzer test.

The results showed a reading of 0.0. The puzzled officer demanded to know how that could be.

The driver replied, "Tonight I'm the designated decoy.”

Comet exploration

In 1985, the International Cometary Explorer (ICE) flew relatively unscathed through the gas tail of comet P/Giacobini-Zinner, at a speed of 21 km/sec at its closed approach of some 7,800-km downstream from the nucleus. The spaceraft found a region of interacting cometary and solar wind ions, and encountered a comet plasma tail about 25,000 km wide. Water and carbon monoxide ions were also identified, which confirmed the “dirty snowball” theory proposed by Fred Whipple(1950). It had been launched on 12 Aug 1978, originally named ISEE-3 (International Sun-Earth Explorer), then renamed ICE when, after completing its original mission in 1982, it was gravitationally manuvuered to intercept the comet.
