On September 19, 1989, UTA Flight 722 going from Brazzaville in the Republic of Congo to Paris, crashed in the Tenere region of Niger. All 170 people on board were lost. The investigation of the wreckage found traces of PENT in the wreckage. PENT is a primary ingredient of Semtex, a plastic explosive. There are other plastic explosives it could be, but Semtex was a favorite of Libyan intelligence services. And the French investigation into the crash found a connection between the Libyan intelligence service and the terrorist group claiming responsibility.
The general belief is that this was revenge for France's participation in the Toyota War. It's profile is consistent with other acts of state sponsored terrorism conducted by Libya, even down to the use of Samsonite luggage.
Eighteen years later, the families gathered to make a memorial for the victims. They began by having rocks brought in from 35 miles away. The crash site sits in the Tenere region of Niger, and it is very much what one thinks of when one thinks of a desert. Large swaths of sand and nothing else.
Then they began to build the memorial by hand. They gathered the stones in a circle and began to fill them in. 170 broken mirrors, one for each victim was placed on the outer circle.
The starboard wing was used to hold the plaque containing the names of the victims.
And the results of two months of labor can be seen from Google Earth.https://maps.google.com/maps?q=16+51.5287,11+57.1418&hl=en&ll=16.86501,11.953699&spn=0.004292,0.006968&sll=33.881798,-117.85029&sspn=0.085364,0.094585&t=h&z=18
