Operation
The MSC's usual method of operations was ‘porpoising’ in quick rises to the surface to check bearings, then shallow diving. Porpoising is when the pilot puts the bow of the Sleeping Beauty to the water's surface and watches the reflection of it underneath the surface, and just when the bow was about to meet with its reflected image the Sleeping Beauty is put in a dive so that the pilot's head would come out of the water and he was able to see his direction.
The pilot could leave the Sleeping Beauty to swim and plant limpet mines on enemy ships, rather than piloting the MSC to the target directly.

Famous quotes containing the word operation:
“Human knowledge and human power meet in one; for where the cause is not known the effect cannot be produced. Nature to be commanded must be obeyed; and that which in contemplation is as the cause is in operation as the rule.”
—Francis Bacon (1560–1626)
“It is critical vision alone which can mitigate the unimpeded operation of the automatic.”
—Marshall McLuhan (1911–1980)
“An absolute can only be given in an intuition, while all the rest has to do with analysis. We call intuition here the sympathy by which one is transported into the interior of an object in order to coincide with what there is unique and consequently inexpressible in it. Analysis, on the contrary, is the operation which reduces the object to elements already known.”
—Henri Bergson (1859–1941)
