"Can I take pictures on a commercial airplane?" The short answer is yes. The events of September 11, 2001 temporarily banned airline passengers from taking pictures in commercial aircraft, as of April 2010, there are no Federal Aviation Administration (FAA) regulations that restrict still photographs on airlines.

While there are no existing FAA rules prohibiting still photography on airplanes, if your flash disturbs other passengers, flight attendants may ask you to refrain from using your camera. In such cases, federal regulations require that you follow the instructions of flight attendants during your flight.

But the problem is video cameras have no ruling from the FAA yet, so video cameras may be banned from the airplane company side, but not illegal in the FAAs guidelines. These days the phone is a video camera as well and this is why passengers may be asked to refrain from using their devices. Plus other passengers may feel uncomfortable when they do not wish to be in your video segment.

If taking photos and video was illegal on a airplane, they why do the stewardesses not mention that when they state that smoking is illegal on a airplane. Many photographers offer stock photography of airplane photos.

However taking photos of military aircraft may be an issue.

My friend Art called and mentioned that he was a airplane pilot for 40 years. He knew right away what the airplane bolt hanger is used for. On some planes there is one exit door over one wing, and on other planes there are two exit doors which lead onto the wings of the aircraft. The exit door is like a plug, it is tapered inward which prevents it to release outward. The door once opened first has to come into the aircraft to be turned, then to be thrown out of the exit door hole. Once the door is out of the way, it reveals a pocket on the top of the door frame which has a strap and clip pre attached to the plane. The strap is clipped to the bolt hanger on the wing, which gives passengers something to hold onto when first stepping out and standing onto the wing.

The painted bolt hanger is riveted or welded to the airplane wing, aligned to easily cut through the air. This is why the clip goes on the side of the hanger, instead of being in correct hanger alignment for the greatest load. Art never heard of photo taking being banned from aircrafts.

So now every time I get onto a plane and look at the wing bolt hanger, I will feel almost satisfied. I will be complete once I have one in the museum. Okay back to researching on how to obtain one of these gems!



This may also solve the Twilight Zone episode with William Shatner. It wasn't a monster on the airplane wing, it was a Yetti going for the clip.

Roots, Not sure if that bolt hanger is homemade but it looks like a cut piton. I have the same item with a "G" stamp but the eye is on the other side. Possibly an early Grivel piton, but I have two others the same shape with a "V" stamp (possibly Wally Vegors), and a "CRS" stamp. Hmmmm....

Marty- Those are Gerry blades with the one on the right likely thinner and a bit earlier in the production timeline hence a bit rougher in shape and finish. Readily available for modification into into funky bolt hangers.

Roots- Somebody was making those ring and strap hangers commercially because the work is pretty clean. They might have been sold as a masonry anchor apart from specific climbing use as I have seen them out in the world during my time as a builder. Plenty of home made ones around too.

^^^^^^
The first bolt in the photos from Switzerland looks like a Mammut ring bolt. Christain Griffiths used those on some hard FA's in the Boulder area in the mid to late 80's. The have a pin in the back which expands the end of the bolt when pounded in. They are a pain to replace.

The second photo has a bolt which looks like a plated, 10mm wedge bolt.

Here is a bolt/hanger I pulled out and replaced yesterday (with Fixe SS hardware). It is stamped, Altus made in Russia. Titanium I guess? The bolt is obviously very rusted.

I also removed a hanger stamped "Lucky".

I replaced a couple of these a few days ago near Tahoe. I thought it said "Lucky" but it doesn't. Some strange characters and then "cKY". Also says "Spain" on it. No big deal, but amazing how many different hangers there are out there!

Hey Marty,
Not sure if you're looking for the answer but I don't see that you ever got back to bhilden's suggestion up thread, regarding RK.

Rupert Kammerlander used to stamp his hangers RK. I am not sure of his Yosemite climbing experience, but he put up a lot of long free climbs at Pinnacles National Monument(now Park). Hmmm.

He was born in 1940 in Austria and climbed quite a bit in Yosemite, then died in 1978.

Ney Grant,

yes, that Altus hanger is indeed titanium. It is probably ok for a protection bolt, but is a bit soft to have hardware in it, like a quick link, for rappeling.

ionlyski - Yes I added the info to the hanger that it may be from Rupert Kammerlander, but I am not 100% sure that the hanger is his. Do you or anybody have a RK hanger which can be compared to the RK hanger from the Nose route? Thanks for the info on Rupert!


Ney Grant - LucKY hangers are from Spain. The hangers are usually stamped “LucKY and Spain” and the “uc” in the stamp is lower case letters which has a line over the “uc.” It is pronounced not LucKY but more like Looooky.
