These plane crashes over the last week are tragedies. They show us that life is short and sudden. It's an unchangeable truth that we don't have control over. But we can have control over how we respond.

BACKGROUND: A midair collision between an Army helicopter and a jetliner killed all 67 people aboard the two aircraft, officials said Thursday. It’s the country’s deadliest aviation disaster in almost a quarter century. The plane carried 60 passengers and four crew members, and three soldiers were aboard the helicopter.

Following this tragedy 6 passengers of a medical jet and one person on the ground were killed after the plane crashed in a Philadelphia neighborhood on Friday evening, officials said.
