US Coast Guard searches for missing Gulfstream jet near Nantucket

The US Coast Guard launched a search operation on Saturday for a Gulfstream G100 jet carrying six people after contact was lost early Saturday morning.

The twin-engine jet took off from Bermuda International Airport late Friday evening and was heading toward Boston, with current search efforts concentrated off the coast of Nantucket.

Tracking records indicate the aircraft underwent a dramatic descent in altitude before radar contact ended, while the causes and passenger identities remain undisclosed.
