Investigators recover black boxes from cargo plane crash in Miami

Homendy did not offer details on who was killed in the crash, but said they were from the two vehicles struck on the ground. The van contained a team from Professional Ocean Service Corp, which provides cleaning services for airlines, and the SUV beyond the airport perimeter fence was traveling on Northwest 67th Avenue, she said.

The Amazon cargo plane was on its third flight of the day, coming from San Juan, Puerto Rico. It had flown from Cincinnati to Miami, and from Miami to San Juan, earlier on Sunday before the crash at 1:53 p.m. EDT (1753 GMT), Homendy said.

Part of the NTSB investigation will examine the significance of the lack of runway material designed to stop runaway aircraft. Not every U.S. airport has an Engineered Materials Arresting System, or EMAS.

Homendy also asked the public to send in any photos or videos of the scene, saying those images could aid the investigation.
