(I figured I will finish this scene off as a bit of a head start, since the next chapter is already beginning.)

The green flares are lit, the survivors begin to take off from the hanger bay, soon all who could escape the ship by air are in the corvette, all on the ground who can be rescued are rescued. The corvette crowded and bustling begins to fly off to leave the planet with enemy fighters bombers and gunships in pursuit, the corvette is 15 minuets away from exiting atmosphere, and opens a slip space portal. Suddenly massive amounts of fire power strike the corvettes thrusters, it can't gain any more altitude and enter, it begins to go down. But, enough thruster power plus reversing grav lift nearing ground level is still able to be used to control and soften the crash to steer the ship as far away from the blast radios as possible before it inevitably hits the ground.
In the process 5 minuets before the crash all perusing air forces have been managed to be shot down, currently ground forces lost track of us. Some of our own on the ground are still making their own escape on foot and by vehicle. Others are either stuck somewhere have already retreated on their own or where unrescueable and still stuck inside the blast radios.
Ships self destruct to go off in 15 minuets. https://www.youtube.com/watch?v=nlZ0QUhp4n4
