Up 'til that point, he'd only fired one at a time, at towed socks. *note that Johnson left that part of the tale in when he revised and re-released Thunderbolt! Jeff I can't imagine that, while firing all eight of those .50's in a P-47, that the whole plane wasn't shaking....much less just the stick. Anybody with shooting experience in that plane care to detail their experience? Dave Never flew the P-47 but firing the six guns in the Mustang created a lot of noise but little if any vibration. Certainly didn't shake the stick. Howard Austin |

Certainly didn't shake the stick. I suppose it's quite difficult to portray vibration that can only be felt, without resorting to subtitles. One piece I read was of a Lancaster pilot who said that on full revs as the Lanc' lurched forward at the start of its take-off run, the control column felt like you were holding a hive full of angry bees.

Subject: Stick Shake When Firing Guns
From: "Richard Brooks" Date: 9/28/03 4:41 AM Pacific Daylight Time Message-id: Firing the nose gun on a B-26 didn't provide enough vibration to tumble the Norden gyro. And it takes damn little to tumble a Norden gyro. There was more noise than anything else. Same for the 4 package guns on the Marauder.

I've noticed that on the camera gun film shown on some TV programmes sometimes the whole picture vibrates and at other times it is quite steady. Mike -- M.J.Powell |

Mike Depends largely on the installation of the gun camera, and its position relative to the guns. In the P-38, the camera was initially installed in the nose, pretty much just below the 20mm cannon. The result was very poor to unusable footage. The camera was later moved to one of the underwing pylons, and the result was very steady gun footage, if from a somewhat unusual perspective. Mike |

The cameras in many of the fighters in the ETO had a seperate switch for turning it on and off. You can sometimes see a little flag in the uper left or right of the frame that indicates trigger pull. On some the flag means firing and some its absence means firing! So a single film shot can have firing and nonfiring portions and sound affects are often added to match the vibrating portion. You also get some shots of enemy pilots under their chutes. This is done with the camera switch, uhm, most of the time. A good example is the famous very long chase at treetop level by Harry Dayhuff (or someone in the 78th) in a P47 that culminates in his blowing the left wing off a German plane. On the P47 the camera is mounted in the wing and you see a lot of vibration, mostly due to the low shutter speed of about 1/30 sec. Since the P47 was very heavy and double skinned, the pilots I have talked to never mentioned feeling much in the way of vibration. -- Charlie Springer |

In the case of the A-10, I would figure that everything
in the immediate vicinity of the cannon would shake when it was fired. -- --Matthew Saroff Shrub stole the election, and all I got was this lousy T-shirt http://www.pobox.com/~msaroff/liar |
