How come my aircraft don't fly completely across the screen

[Spookie71]

Hello

I am playing the tutorial scenario with the US and Iraq.

My question is why doesn't my A-10 Warthogs fly right across the screen.

I have gone into Air Entry and Exit and set the A-10's to fly from right to left across the screen.

What actually happens is the A-10 appears on the right hand side of the screen and fires it's ordnance and then just disappears.

Can you let me know how I can get it to fly all the way across the screen.

Thank-you,

Scott
