Holy Moly. That is one tough mission. After reading the posts I found out I'm doing it all wrong. I was attacking the planes on the right side of the field not the spawn planes. I even went after AA guns as well.
Does anyone know what the mini missions are like?

lol rabaul is hard after reinstalling the game and starting the missions all over again i was surprised to pass rabaul on my first go.

the next mission god it took me a few goes lol jford can be tricky not hard but you can crash alot

as for the mini mission they are easy but really fun

when complete it upgrades youre guns and rockets
arcade is the one u want to complete pick the planes you fly and can handle the best
do the missions and get the upgrades its not much but you can feel the difference

ace paint it justs give u paint lol
