Liberty Ship v2a

This file contained a postwar version of the Liberty Ship (i.e. no guns) and a revised aircraft.cfg for my WWII version. Some people have noticed that, after installing the revised aircraft.cfg, their WWII ships are now cruising a lot slower. This was intentional.The original WWII version was cruising at 25 kts. However, the real ships cruised at a maximum of 11 kts. So I changed the thrust setting from static_thrust = 180000tostatic_thrust = 125000If you want your speedy ship back, just change that line from 125000 to 180000 - or whatever value you want.Enjoy!Captain Phil
