Federal investigators were working Tuesday to find out what led a pair of private jets to collide on a runway at a small airport in Scottsdale, Arizona, killing one person and injuring several others.

At least one person is dead and three injured after a small business jet crashed into a parked plane as it arrived at Scottsdale Airport in Arizona, just east of Phoenix, on Monday afternoon.

One person was killed and four others were injured during a plane crash Monday in Arizona.
