Question bout Aircraft

[CSA FD]

ok, ive completed brit supplies/costal waters and the total Germany campain, my question is: AIRCRAFT, i see them constanly on the map, and alot of the times they fly directly over head, and i target them with my AA and they fire way below the targets, i got one where i was the one aiming (swordfish, which doesnt have much speed) how do i get them to aim @ the aircraft and do aircraft even attack subs? (not that i want them too, just wondering)

oh and i just love the ammo bar right in the sight line (NOT) :down: also ive gone from Nov 1940-mid Jan '41 and lack maybe just 2 of the 10 ships required and i cant find anymore, gone to harbors, ran into convoys, and lone ships, and out of the 19 ive sunk only 3 have been the required ship. :-?

IRAI causes aircraft to attack you on sight. Press Shift+Z to hide HUD ( and that DAMN ammo bar!) The war supplies ships are always large steamers/liberty cargos. 1 out of 3 large steamers/liberty cargos will be carrying war supplies. If you don't want to do this objective at all, use any version of Open Horizons II.
Good luck!
