Last night a dramatic accident took place above Switzerland : a Tupolev plane from a Russian company and a Boeing from the DHL company have telescoped while cruising at an altitude of 11 000 m.
According to first information, the Russian pilots have misinterpreted instructions from flight controllers. Which could mean: "Russian pilots, not familiar with units commonly used for expressing altitude in world civil aviation (feet), are responsible for the crash". If this explanation is confirmed, how should we react? Louis
