In april, 1995, Giuseppe Stilo started to organize materials and ideas for a new, specialized Italian UFOs catalogue. From the first collection and classification of events an informatic catalogue was derived, named CRASHCAT. Presently it contains 163 entries of reports about the fall and the certain or probable crash of flying objects on the Italian peninsula and the surrounding seas, excluding all reports of following take-off. The CRASHCAT events are classified in three mutually exclusive categories:
- objects that were seen falling on the ground and were located or retrieved;
- objects that were seen falling on the ground and were not located nor retrieved;
- objects that were seen falling in fresh waters or sea waters.
The following reports are left out of CRASHCAT (which also includes reports of falling objects probably identifiable as manmade or meteoric in origin):
- reports about "things fallen from the sky", traditionally connected to the so-called "fortean" phenomena, or to unusual meteorological events (fall of ice pieces, or of fishes, or of other animals, etc.), that are considered more pertinent to FORTCAT project (see this item);
- reports about objects or phenomena associated with complex "manoeuvres" above water surfaces, even when the conclusion of the "manoeuvre" is an immersion;
- reports about objects or phenomena that touched ground or water surfaces, but whose supposed "take off" to the sky was not observed for circumstances other than the plausible conclusion of the same phenomena, i.e., tipically, the witness(es) leaving.
As of now, the project has recorded about a hundred cases, from the analysis of which a high percentage of cases results that could be explained as sure/probable/possible misinterpretation of (in a decreasing number):
- fall of weather or other balloons;
- fall of meteors or meteorites;
- fall of pieces of piloted or radio-controlled aircrafts, or of artificial satellites;
- hoaxes or forgeries;
- other conventional causes.
