Malaysia Airlines Flight 17 with 298 people aboard was apparently shot down by a surface-to-air missile, according to U.S. and Ukrainian officials. The commercial Boeing 777 — en route from Amsterdam to Kuala Lumpur — crashed Thursday afternoon in eastern Ukraine, with no survivors likely. The flight fell off radar about 20 miles from the Russian border. Eyewitnesses reported seeing debris falling from the sky. Ukrainian and separatist leaders traded accusations over who holds responsibility, although Ukrainian military planes have been hit by missiles recently in the ongoing crisis with pro-Russian separatists. Major airlines, such as Delta and British Airways, have steered their planes clear of Ukrainian airspace in an abundance of caution.
