Dick Perry ran this photo and a story about the Marine Corp Air-Ground Museum in his Model Aviation column - October, 1991.  The photo was nowhere near the quality of this one (due to being a non digitized copier machine scan, probably).  Just out of curiosity, where did you find this one?  Do you happen to have a larger resolution copy of this one you could email me or post here?  Would be interested in replacing the old photo in my scale documentation folder.

As to the caption, someone obviously mixed up the caption intended for a different photo.  This photo would have been taken after the Langley was transferred to San Diego.  I also have found documentation that VF-1 (the Navy's oldest fighter squadron) operated one MO-1 while attached to the Langley as an "Observation" plane.  Their fighters were NAF/Curtiss TS-1's.  VF-1 has morphed into the VFA-14 Top-Hatters.  This was the sister squadron to VF-32 (my squadron), aboard John F. Kennedy during JFK's 1st two cruises (1969-1970).

Here (and in a couple more posts) is the 1991 article.

Glad you found the photo, I just stumbled on it surfing for pictures of carrier planes (because that is all we can do in the DC area now, Since model airplanes are outlawed around here), I am thinking of getting into FPV Drone racing. They do it indoors so the FAA does not have jurisdiction.

An interesting idea. There are some places big enough that allow RC indoors. It would be great for me, but most folks in this area still fly glow planes. Right now the closest place I know that we could fly at is about 60 miles away. There is another possibility but it is even farther.

Just found another even earlier -





Now I HAVE TO GET BACK TO WORK.  You guys are a bad influence on me.
