TWO French fighter jets screamed across northern Mali on Thursday not in pursuit of terrorists, but on a far more tragic sortie. At 1.50am Air Algeria AH5017 disappeared, possibly over the country. The plane was an MD-83, carrying 116 people from Oaugadougou, Burkina Faso to Algiers. Onboard were passengers from France, Burkina Faso, Lebanon and elsewhere, and a Spanish crew. Its pilots were apparently told to alter course to avoid bad weather before contact with the flight was lost. Algeria has sent a C-130 aircraft and Mali is also looking, but the French military lead the search.
