Abstract
The reliability of the Input Catalogue is one of the keys for the success of the Hipparcos mission. As the Input Catalogue is a catalog made of very heterogeneous sources, many systematic reliability tests were conducted to eliminate errors on identifications, position, magnitude, etc. In March 1991, half of the Input Catalogue had already been checked by the 'First look' facility developed by the FAST consortium at Utrecht. It is shown that less than 0.1 per cent of the 118,000 stars of the observing program will not be detected.
