My father, CWO Charles O. Laine, is pictured in what appears to be an ejection seat mockup in the Gemini program in September of 1963. I have seen similar photos of the Gemini astronauts in the same but was never sure as to what they were testing and why. Any assistance would be greatly appreciated. Note: His Gemini G-2C training suit was made on Aug. 6, 1963, one month before these photos were taken. I am still looking for his helmet and gloves. His suit is being stored at the U.S. Space & Rocket Center in Huntsville, Alabama. <UL TYPE=SQUARE><LI>Helmet: GH-2C-2 Size Laine <LI>Gloves: GG-2C-2 Size Laine</UL> <center><a href="http://www.collectspace.com/review/wlaine/gemini_ejection01-lg.jpg" target="AirLock"><img src="http://www.collectspace.com/review/wlaine/gemini_ejection01.jpg" width="400" height="327" border="0"></a><a href="http://www.collectspace.com/review/wlaine/gemini_ejection02-lg.jpg" target="AirLock"><img src="http://www.collectspace.com/review/wlaine/gemini_ejection02.jpg" width="400" height="524" border="0"></a></center></TD></TR><TR bgcolor="#333333"><TD valign=top>David C</TD><TD>The top picture looks like a fit check to me, I think that's a partial hatch mock up.I've not seen similar Gemini astronaut pictures.

There are adjusting screws in different places that support this idea. The hatch mockup is interesting because it combines both the left and right hatch contours at the astronaut's seat. I notice that the tubes on either side of the helmet seem to line up with the eyes. Eye placement was an important parameter considering that the instruments, window, and other features presumed a certain eye point. And I think the raised position (second photo) was to relieve body pressure points.Why the plastic sheet?

Thanks Oly, fun footage. Particularly surprised to see Armstrong trialing a non conformal "goldfish" helmet. Didn't know they were considered for the X-20. The poster has a sense of humour, the Right Stuff and James Bond.

Didn't really see any (non-pressure suit) equipment similarity though.

Oly - is there a link to that video or do you have it where you could send it to me? Thanks!

I found the video while looking for some details on the Dyna Soar project during a google search, it is titled "Astronauts Grissom, Schiara and Armstrong Test the X-20 DynaSoar Cockpit & Space Suits." There is a part 1 and 2 available.

A photo of Armstrong wearing the bubble helmet is seen here:

Thanks Oly. The guy in the silver suit on the X-20 video looks like Pete Knight to me.

Lou Chinal

Yes, it's Pete Knight. But I didn't know he had a Mercury suit.

Lou Chinal

Thanks for the question, Bill Laine.

Pete Knight SR-71 speed record post flight damage video and flight video.

Amazing how the X-15 ejection seat could be used to speeds up to Mach 4... in theory!

I am not 100% convinced that these photos are for the Gemini seat, I don't see any familiarity with the mock-up of the cockpit shape and the Gemini spacecraft. I have tried to overlay photos of the Gemini seat with these photos. It would be nice to see another view of this.

Philip

Looks similar to the weight and balance seat used for the Gemini program...

As I mentioned earlier, in the first photo the white arch shape to the left (above the head of Mr. Laine) appears to me to be a combination of the left and right hatch areas above the Gemini seat. The critical fit area would be where the seat is closest to the conical hatch. I think this jig allowed evaluation of this critical area on both sides simultaneously.

I agree that this does not look like a Gemini seat, but it does resemble it generally. That's why I think it's a very early check of the intended seat dimensions.

oly

The seat appears to be made of wood and plate metal, which is why I believe that it is either a jig of former for casting the seat mould. I do agree that there is not any materials surrounding the technicians or engineers, the floor appears to be covered with paper, taped down to protect the surface, it has been torn in several places.

In these shots I think they are checking the fit, not actually casting the seat, but I do believe it is a casting fixture. It also may be true that the fixture is an ambidextrous form, suitable for either side. this may account for the head box area shape.

The date and style all align with the Gemini program, the seat head box differs from the Dyna Soar shape, leaving Gemini as prime candidate.

The fourth photo on this page, taken in Hanger S, shows Scott Carpenter during a suit fit check.

Related to my original question above, I found this photo of astronaut Neil Armstrong sitting in what appears to be the same type of apparatus my father was sitting in for the testing he was involved with on Sept. 16, 1963. I don't know what date the Armstrong photo was taken but apparently this was a similar testing process.

Perhaps my father's tests were related to the development of this process. Just a guess.
