Why does the crash dive go to ~70m?

Answer to the original question: When you conduct a normal dive the tanks are flooded and the sub is taken down. American practice was to dive to 100 feet and then come back up to periscope depth once proper trim was assured. I'm betting German practice was the same, so "Periscope Depth" is not realistic from the surface, nor is "Decks Awash".

In an emergency 'crash' dive, everything is flooded, the boat is taken to flank speed and the planes are put on full down. Several hundred tons of steel is hard to stop once it gets going downward, so 70 meters is, as I understand it, the depth they really did pull out of.

If you want to go to 20 meters, click "20" on the dial and order flank speed. You should get there faster. If not, blame the game.
