deep raid

[hampshiresid]

Hi,
I"m what you would call a senior citizen gamer but enjoy playing x box games.
IL2 Sturmovik is brilliant but I am stuck on "Deep Raid". I"ve flown over the 2 aerodromes and then flown on to Stalingrad where I"ve tried to bomb all the ground targets, but I keep on coming up against a "Run out of time" warning which doesn"t allow me to carry on.
What am I doing wrong or more to the point, What am I supposed to do?
Any cheats, help etc would be appreciated.
I haven"t got a joy stick which I imagine would make the game more enjoyable, so should I buy one?
My next buy will be Moto Gp 2010/2011, has anyone got it and how good is it?
Cheers
Dave
