My dad was a right waist gunner in the 458th BG of the 8th AF stationed at Horsham St. Faith in England in early 1944. He flew 30 missions.
The Liberator was a much more modern aircraft than the B-17 Flying Fortress. It would fly higher, faster and carry a larger load that the Fort...but it could not take the damage the Fort could. My dad said the B-24 had a nasty tendency to leak fuel into the fuselage...so they always were careful to smell for it and put out the smoking lamp if they smelled gas.
One mission, he was coming back to England all shot up with two engines out...over the channel, low altitude, trying to be as invisible as possible, when he saw a single fighter diving down at them from far away to the starboard quarter. Figuring it was a Jerry ME-109 looking for an easy kill, the Old Man called out the fighter to the other gunners. Just as he about got into .50 cal range, the peashooter driver pulled out of his dive and turned right to show his profile, that of a Mustang. The Old Man was one happy camper. That Mustang driver followed them all the way back to their base in Norwich, weaving back and forth, guarding them...then peeled off to go home. Glad that dude was there...or I might not be here.
Another time, after an especially long day, when the group was coming back home at dusk, they were attacked by a bunch of Jerry night fighters. The first indication the Old Man had that they were under attack was when the plane right next to them suddenly blew up! Then he saw the enemy ME-410 that had just shot down the other B-24 shooting at him...with the cannon rounds flying just below his plane...right about where the waist position was. He told me they looked like big fiery white golf balls flying at them. Although he was the armor gunner and knew better than to fire long bursts, he was so scared he just held the trigger down and the Kraut flew smack into the bullet stream as he roared below the Old Man's plane. The Old Man got lucky with his shooting, because he killed the Jerry pilot. Since they were only about 500 feet up...the Jerry crew never had a chance. The Old man went out the next day and they looked the wreck over. Funny thing: As the attack began, the tail turret gunner called out to the Old Man to come quick and help him put his Ma Deuce breeches back in! Seems the guy had a squeeze in town and he was trying to save time upon landing by dismantling his guns to save cleaning time before they landed! The Old Man told me he just yelled at the tail gunner over the intercom that he couldn't help him right at that minute, he was sort of busy!
I got into the Strawberry Bitch once...amazing how small it was. Never could figure out how the Old Man and the other waist gunner stayed out of each other's way.
Brave men and a brave and patient home front. I only hope we are as determined and brave as our parents were.
