Scapa Flow East entrance guide and maps.

[SmokingHeadStudio]

My Mission in Scapa Flow in SH 5 was:

Drive inside, kill 3 Ships,go outside, be followed from 1 Destroyer.

So: go on, and see that you can move away.
Turn on the Periscop, watch around - nothing -
Come up to the Daylight

... and the Destroyer falls from the Sky, exact to the Location of my Boat.

... we all was Death in 1 Moment LOL
