A seaplane with 20 people exploded in mid-air and crashed off the coast of Miami Beach, Florida, Monday afternoon, killling all aboard. Nineteen bodies have been recovered and one is still missing.

The propeller-driven aircraft crashed shortly after taking off from Miami enroute to the Bahamas.  Authorities say the cause of the crash is under investigation.

The plane went down in Government Cut, a channel that cruise ships and freighters take into the Port of Miami. Authorities say the channel, a major shipping route for the southern United States, has been closed until further notice.
