This led to the development of an extremely important modern instrument: the Cherenkov counter. It is made of some transparent substance such as Lucite. When a proton, electron or other charged particle enters it at a speed that is greater than the speed of light in the material, Cherenkov radiation is given off. Its angle (like the angle of a ship's bow wave) depends on the speed of the particle. When the angle is measured by a photomultiplier tube, the speed of the particles can be determined...
TOUGHER PILOT CHECK by the CAA will mean more surprise inspections of airlines' blind-flying skill. Latest check: Northeast Airlines pilots, involved in three fatal crashes in bad weather in 21 months. Of first 95 Northeast pilots tested for instrument flying, five failed...

But the project's scientists promptly warned that such apparent discoveries may prove to be the result of instrument failure or a drop in the power supply of the recording apparatus. The definitive report on Pioneer's findings may not be released for weeks or months...
