justice. The difficulty the investigators and the victims' relatives had in receiving complete, reliable information on the Ustica disaster has been popularly described as un muro di gomma (literally, a rubber wall), because investigations just seemed to "bounce back". Memorial On 27 June 2007, the Museum for the Memory of Ustica was opened in Bologna. The museum is in possession of parts of the plane, which are assembled and on display, including almost all of the external fuselage. The museum also has objects belonging to those on board that were found in the sea near the plane. Christian Boltanski was commissioned to produce a site-specific installation. The installation consists of: 81 pulsing lamps hanging over the plane 81 black mirrors 81 loudspeakers (behind the mirrors) Each loudspeaker describes a simple thought/worry (e.g. "when I arrive I will go to the beach") All the objects found are contained in a wooden box covered with a black plastic skin. A small book with the photos of all objects and various information is available to visitors upon request. Dramatization The crash of Itavia Flight 870 was featured in the 13th season of the Canadian documentary series Mayday in an episode entitled "Massacre over the Mediterranean". The episode discussed the separate investigations into the event, and appeared to favour the investigation led by Frank Taylor, which concluded that the wreckage ruled out a missile and pointed to an explosion in or near the rear lavatory was the most likely. A 1991 Italian film by Marco Risi, The Rubber Wall, tells the story of a journalist in search of answers to the many questions left open by the accident. The film theorises on a few possible scenarios, including the possibility that the DC-9 was mistakenly shot down during an aerial engagement between NATO and Libyan jet fighters.
