They Fled Cuba for Better Lives. They Were Cut Short by a Cargo Plane.

They fled Cuba to build better lives in America. They collected trash and wiped down seats on airplanes at the Miami airport to support their families both in Florida and on their native island.

Then came an unexpected peril: An Amazon cargo jet crashed into their van, killing five and injuring two others.

One of the victims who died, Javierkys Reyes Quevedo, 47, had worked to save for a trip to Cuba in December to visit his teenage daughter for the first time since leaving the country eight years ago. He wanted to celebrate her quince, or her 15th birthday.

“It’s so senseless,” his brother, Yusdany Pol Quevedo, said on Tuesday night.

Mr. Reyes Quevedo was one of five workers with Professional Ocean Service Corporation who were killed when the cargo aircraft, a Boeing 767-300 operated for Amazon by 21 Air, crash landed on Sunday on its way back from San Juan, P.R. Two others in the van were injured, and the driver of an S.U.V., which the plane also hit, was also hurt.

The flight overshot the runway at Miami International Airport upon landing and skidded across a grass field, plowed through a perimeter fence and across a public road, and also hit the S.U.V. before stopping near a parking lot.

Officials from the National Transportation Safety Board, which is leading the investigation into the crash, said in a news conference on Tuesday that they would begin interviewing the airplane’s crew on Wednesday morning. Experts were also reviewing flight recordings from the plane’s black boxes.
