Ustica is the name of a small island just north of Palermo, Italy.

It become sadly famous in 1980, when a DC-9 airplane with 93 passengers was lost some miles offshore.

In the following days, months and years, an unbelievable amount of speculations about military training, underground warfare between NATO and Libya, deleted radar records, rectracted witnesses spawned up without a clear cause for the disaster.

The current (unofficial) hypothesis is that a military airplane shot down the DC-9 mistakenly, but no official version has ever been given, and the disaster cause is still unknown.
