What do you think is happening with all the plane crashes in America lately?

First there was that crash in Washington DC that collided with a helicopter that killed everyone on board, then another in Pennsylvania, one in Alaska, there’s another one I can’t remember where it happened and today a Delta plane just crashed in Toronto. It’s like there’s a plane crash at least once every week.

I’m from Canada, currently on vacation in Hawaii and I’m leaving for home tonight. Even though I’m taking a Canadian airline, hearing about all these crashes is making me nervous! Something is not right with aviation in America at the moment. What do you think is happening?
