Investigators are still trying to find out why an Amazon cargo plane went past the end of a runway in Miami on Sunday.

The crash killed five people on the ground.

The Boeing 767 hit a van carrying a cleaning crew on airport property.

Then it broke through a fence and hit an SUV on a public street.

Five people in the van died, and two others survived.

The pilot and co-pilot also lived.

The plane was landing after a two-hour flight from Puerto Rico.

Storms were gathering near the airport at that time.

It traveled about 1,300 feet past the end of the runway.

Jennifer Homendy, chairwoman of the National Transportation Safety Board, called the scene "utter devastation."

She noted that jet fuel remained around the wreckage 24 hours later.

Experts who watched video said a strong tail wind likely pushed the plane far down the runway.

The plane stayed in the air without lowering its nose to land.

It is not clear why the pilot did not stop the landing.

Air traffic controllers had not changed the approach direction.

So the plane did not land into a headwind.

The crash closed the airport for hours.

More than 225 flights were canceled.

The five victims worked for Professional Ocean Service Corp., a plane-cleaning company.

Amazon said it is cooperating with the investigation.

The NTSB will look at the jet's history, maintenance records, and operations by 21 Air, the cargo carrier that flew it.

The agency will also examine the lack of a runway safety system, which Miami does not have.

Homendy said such systems must be installed to prevent future tragedies.
