Won't landing with the ski crash the plane on the runway because of sparkles? Logically it would have to land on grass or in a field because it is smoother. Am I right?

Still can't get the plane to climb to 10000m in less than 3minutes. I keep stalling...Is there a specific command to activate?

You're not supposed to climb at 80 degrees,.. more like 45-50 degrees.....
After you gain some height, the air becomes less dense and you fly faster and can climb faster.
(its much easier to go vertical at 9000' than it is at 1000' or 2000'.. get what I'm saying? Increase your angle of climb the higher you go.

You have less than 10minutes worth of fuel. Shut off rocket as soon as you reach attack altitude

Climb 1000m-2000m above the bomber formation, shut off rocket and dive steep while firing ahead of the bomer, then zoom climb again and relight rocket.
On each dive / firing pass you can expect to shoot down a bomber.
If you are good/lucky you can shoot down maybe 5+ bombers before you run out of ammo or fuel or both.

Land on the grass next to the runway. Make sure to lower your skid (landing gear) and FLAPS!!!
This is a rocket powered glider
