And about a dozen planes in the last two weeks. Those pesky right-wing extremists! “Bomb threats ground 5 US flights,” by Sophia Rosenbaum, New York Post, June 2, 2015:
Bomb threats grounded multiple flights leaving from various destinations throughout the US on Tuesday morning.
Five flights were threatened, with four of them landing safely.
A fifth flight, Korean Air Flight 23, was still en route to the West Coast from Seoul. It was scheduled to land at San Francisco International Airport at 11:17 a.m. Pacific time.
Around 7 a.m., police swarmed US Airways Flight 648, which had just landed in Philadelphia, to check for any explosive devices….
Similar threats have affected about a dozen planes throughout the past two weeks.
