Before diving operations started helicopter rescue drills where carried out. The Visby search and rescue helicopter have been on standby during all diving operations. Within 20min the helicopter is on site. The Mars is located in a remote area and the nearest chamber is several hours away by land. So having access to a helicopter has been an important safety measure.
