Plane Crash In Iran Kills 168

It’s turning into a grim summer for commercial aviation, with another 168 killed this morning in the crash of a Caspian Airlines Tupolev TU-154 in Iran, CNN reports.

This crash follows the June 1 crash of an Air France A330 into the Indian Ocean that killed 228 people and the June 30 crash of a Yemenia Airways Airbus 310 near the Comoros Islands, also into the Indian Ocean, that killed 152.

The New York Times points out that:

Iran has been plagued by plane crashes in recent years, a record that aviation experts have attributed to the country’s aging and outdated planes, many of them secondhand aircraft leased from Russia.
