I was on my way to the patrol area west of gibraltar when during a routine hydrophone check my hydrophone operator reported
a merchant.I setup an intercept course and soon got visual contact.The weather was perfect,no wind,very good visibility.
Submerged and waited for the ship.It was a large merchant.Measured the speed 7 knots.Lowered the periscope and started
to input the data in TDC.She was 1.5 km away and there was nothing else left to do,just wait until she gets in to the right position.
Nothing unusual so far.
But then the hydrophone operator reported no contact

.I know they are a little lazy,so I checked myself,nothing

.Raised the
periscope,nothing

,made a full circle with the periscope,nothing

.Surfaced,the result was again the same,nothing,
no visual contact.

The ship disappeared.One moment she was there and a second later disappeared.A real ghost ship

.The
only explanation is that it was a ghost of some large merchant sunked before.They come back to hunt us down
