Washington —
A pilot suffering a medical emergency, a plane forced down in Alaska and passenger jets nearly colliding in Boston are the latest aviation incidents under investigation as the busy summer air travel season gets underway.
While each incident is vastly different, all could be frightening for passengers planning to fly as America rings in its 250th anniversary.
The Transportation Security Administration expects to screen nearly 18.7 million travelers at US airport security checkpoints over the busy Fourth of July weekend, between June 30 and July 6.
The latest incidents also come just weeks after four plane crashes happened in four days in the US. None of the crashes were related, but 21 people were killed.
