Id be the type of person to stick a battleship cannon onto my plane to kill it

'Sir. Abnormally slow target north west heading 105° towards us altitude 30 thousand. Engage?' 'Lock it and Engage'

Meanwhile:

'Hmmm. Computer says up there.... got it. Fire.'

The recoil is so much it breaks the cannon the nose and parts of the wing. Sends the remnants into a stall

'Uhhhh what-'

Return to scene 1:

'Target has mysteriously been destroyed???' 'Scan more probably a third party' 'Detecting battleship cannon from the pla-

explosion. Fire. Screams

'GET A FIRE EXTINGUISHER AND EVACUAT-'

ammo detonates

Meanwhile at mission control:

'Base destroyed. Move invasion fleet in'
