Already began my new career. Yes, the Petes are dead annoying. I can't surface at daytime at all, and once I've been spotted even though I crash dive 1 minutes before they reach my position they always accurately drop bombs onto my previous position

Though I haven't actually got hit it do ruin my daytime interception since I'm always push down to submerge...
BTW, I found that the air search radar seems doesn't work at radar depth. I always go to radar depth to check if any aircrafts near by before I order surface, however everytime when I put my sub on radar depth it tells me "all clear" but after I surface it suddenly tells me "radar contact" and "aircraft spotted" at this time only, in which almost kill me for several times
