Five kilometers below the sea surface, a streamlined submarine floated quietly in the bottomless trench and moved slowly forward. The word "Parrot" was printed with white paint on both sides of the submarine, and the symbol of the Beluga Station was at the center of the radar cover.
There was no need to worry about being discovered by the USN destroyer because its current depth had far exceeded the maximum submersible depth of military submarines. This depth could only be reached by scientific research submarines. No sonar was capable of detecting any presence in this depth, nor could any depth charge or sonar threaten its existence.
In contrast to the quiet movement, the inside of the submarine was already filled with joy.
The two pilots high-fived each other and the observer put down his headset and whistled in excitement. At the door of the control room, the captain, with his arms crossed in front of his chest, grinned under his unshaven mustache.
