A Boeing 727 chartered by Air France with 53 people aboard slammed into a fog-shrouded mountain just after takeoff from the capital, Bogota. At least four bodies were immediately recovered from the debris, and rescuers found no sign of survivors. The aircraft, leased to Air France by the Ecuadorean airline TAME, was bound for Quito, the Ecuadorean capital, a civil aviation spokesman said. It was carrying 43 passengers and an Ecuadorean crew of 10, an Air France spokesman said. Most of the passengers were French and Ecuadoreans who had arrived on an earlier flight from Paris.
