Regular air cargo operations at the Miami International Airport (MIA) have largely resumed after an Amazon Prime Air freighter crashed earlier this week.

A Boeing 767-300 Prime Air aircraft operated by 21 Air overran the runway when touching down in Miami on Sunday, MIA posted on X. Five people died as a result of the crash, according to the Miami-Dade Sheriff's Office. The jet had departed from San Juan, Puerto Rico.

As of Tuesday, two of MIA’s four runways remain closed, according to MIA’s website, which didn't specify when the runway would reopen. The National Transportation Safety Board needs to document the scene first, and "it is not a completely safe scene" for the agency just yet, Chairwoman ​​​​Jennifer Homendy said in a press conference Monday.

"We hope that we can move through it swiftly because we know it is impacting flight operations here, but we have to make sure that we're able to get access to the aircraft first," Homendy said.
