There may be no issues here.....see this note from Aggressor sent to its agents:
Dear Agents,
Greetings from Aggressor Adventures. Unfortunately, yesterday the Red Sea Aggressor I suffered a fire. After everyone was accounted for at the muster station and the order to evacuate was given, one guest apparently decided to return to their room during the evacuation to retrieve something and is missing. All other guests are safe.
The yacht owners are working on a replacement vessel for all the next trips and will confirm as soon as we have the details. Please know that we are working around the clock to take care of your guests.
Regards,
Aggressor Adventures™
