From Patch.com:
Company CEO Marc Wolff told Patch that the missing crew member is 68-year-old Robert Hopkins, who has been with the company only a short time but is an experienced pilot.
"Excellent pilot. He has flown with the major airlines," Wolff told Patch. "He has been with us probably four months, five months right around there. Solid guy, solid pilot."
Wolff said first officer Rolland Silva was rescued by the Coast Guard and is in stable condition at Jackson Memorial Hospital.
