No Bullets Fly by Sabaton
True story .
The Charlie Brown and Franz Stigler incident occurred on 20 December 1943, when, after a successful bomb run on Bremen, Charles "Charlie" Brown's B-17 Flying Fortress was severely damaged by German fighters. Luftwaffe ace Franz Stigler had the opportunity to shoot down the crippled bomber, but for humane reasons, he decided to allow the crew to fly back to RAF Kimbolton in England.
From down below one enemy’s spotted
So hurry up, rearm and refuel
But through the bomber's damaged air frame
See wounded men, Scared to the bone.
Look to the right and then look again
And see the enemy in the eye
No bullets fly, spared by his mercy
Escorted out, out of harm’s way
Fly, fighting fair
It’s the code of the air
Brothers, heroes, foes
Honor in the sky
Said goodbye to the Cross he deserved
He risked his life 2 times that day
To save an unknown enemy
Escort to safety, out of the killzone
A short salute, then departed
