In the course of just one week, two commercial passenger airliners have crashed. On Sunday, February 11, 71 people lost their lives when an Antonov An-148 airliner crashed shortly after taking off in Moscow. Seven days later, on Sunday, February 18, 66 people were killed when an ATR-72 crashed an hour after leaving Teheran airport.
