NYGM + Aircraft

[Steeltrap]

This is a copy of a post I put in the mods room but I've had no response there as yet.

================================================== ============
OK, so I got NYGM 3.0 running.

First patrol, set sail 6th Sept 1939 in a new VIIB, bound for AM18.

Followed usual course NW along deep water off Norway, skirting the continental shelf of the North Sea.

Eventually that leads to a westerly course, well north of Scapa etc.

Now, weather 13m/s, no clouds, no precip, light 'sea-mist'. Running at 7kts - no point in bashing into these seas and wasting fuel.

I figure the war has been running only a week or so - was 9th Sept. by the time I was north of the Orkneys. Likelihood of aircraft should be low, and their chances of seeing me at this speed in these seas should be lower still.

Well.....

Watch crew calls out about an aircraft spotted. 2 Hurricanes, closing fast. Crash dive!

Cannon shells etc all over the place, reports of damage.
Levelled off at 80m then took stock:
- minimal damage.
- several crew wounded.
- hull integrity 79% - WTF???

So I figure I was unlucky. Wait several hours then surface.

Within 28 minutes EXACTLY the same thing happens.

Wait until dusk. Surface.
Within 24 minutes, EXACTLY the same thing happens.

Right....wait until dark. Surface and run until dawn.

Sure enough, within about 30 minutes of light - EXACTLY the same thing happens.
Now my hull integrity is down to 39%!!!!!!!!!!!!!!!!!!

My questions are:
1. is this now 'normal'? This seems to me to be entirely over the top for that part of the sea in that weather at that date.

2. Does the fact that aircraft appeared within 25 minutes (+/- 3 minutes) from the time of my surfacing (or there being enough light to rate as 'day') indicate a problem? Smells pretty fishy to me. Bear in mind I had barely enough time to recharge batteries before the next attack. This is even when I remain submerged for hours after the previous attack.

3. Surely reaching 39% hull integrity without anything other than 20mm cannon shells hitting me is getting a bit absurd??

I understand aircraft are a thing to be feared, but if this is how it is on 9th Spetember 1939 I think it has gone waaaaaaaaaaaay too far. Have things got to the point that, if travelling ANYWHERE that might have air coverage, irrespective of date, you need to remain submerged during daylight?

Would like to hear from others about their experiences under 3.0.

Don't get me wrong - I really love NYGM (and was enjoying GWX until I got sick of the instability problems my machine seemed to be having, which is entirely possibly due to an error on my part in installation). Just want to see what others are experiencing.

Cheers
