The 303rd Bomb Group, the famous "Hell's Angels", has one of the web's best bomb group sites. After posting my photos of flight gear, I surfed onto theirs, and it's a must for anyone interested in high-altitude bomber crew flight gear.
The web page for the flight gear is: http://www.303rdbg.com/uniforms-gear2.html
Here is just one example:
"Photo #12 - In the above photo can be seen the 4 lines of survival that ran from the crewman's fight gear and plugged into the airplane. The large green hose is for oxygen. One black communication line runs from his A-11 flight helmet earphones. The second black communication line runs from his push-to-talk switch. The push-to-talk switch is plugged into the internal microphone of the A-14 mask. The 4th line runs from his F-3 electric suit. The lead cord or extension cord is shown unconnected. Hanging from the sleeve of the left wrist is the connector for the gloves, and just below I've opened the glove to expose the connecting points. The flak helmet is the type M-3. This flak helmet was the same as the G.I. steel pot worn by the infantry, but altered slightly with the addition of ear flaps to fit better over the flight helmets. The M-3 did not have a separate liner that slipped in and out. When you run your hand over the top of the M-3, it feels like fur. A flocking was sprayed over them to keep the guys bare hands from freezing to them. It showed up in 1944. Much of what is displayed here can be seen in the photo of 1Lt Ted Misthal. Examples of the M-3 flak helmet and a flak vests can be seen here." --303rd BG Website
