Authorities Trying to Determine Cause of Plane Crash

An investigation is still heavily underway concerning the cause of a Ukrainian plane crash that left no survivors yesterday. The plane took off from Tehran’s international airport with 167 passengers and nine crew member aboard and crashed a few minutes later. Originally, terrorist attack was ruled out as the cause, favoring mechanical failure as more likely. But now officials are backtracking those statements. They say they are now looking into “all possible causes” including terrorist attacks. They do believe it’s unlikely the crash was a result of crew “error” as they were extremely well trained. The black box was located and is being reviewed by Iranian officials who refuse to turn it over to Boeing or the U.S. One thing we do know is the plane caught fire and quickly changed course before it crashed. The names of all the victims have been released. No Americans were aboard but 63 Canadians were killed.
