They've put in a new video board, it's really impressive.
I'm kicking myself for not taking any pictures of the meal itself, but our guests arrived today and we settled in for an excellent meal. Before they got here of course, there had to be entertainment to keep a homesick someone occupied with her Dad on the way.
A small Thanksgiving with just Mari, Dad, Mackenzie and me. Steak and hamburger provided by G's Meat and Dad's barbecue.
It's Thanksgiving, and even though we're putting of the main meal until Saturday when Lonnie and Payton can be here, you still have to do the traditions. Can't miss the Macy's Parade!
With decorating pretty much done, Mari and Mackenzie moved on to a little gingerbread house building. Though it turned out to be a bit messier than expected as the frosting "glue" that came with the kit didn't seem to work so well.
While Mari and Dad rested for a minute I took Mackenzie through the indoor display area, featuring frogs, snakes, bugs and other critters like this crocodile.
The silk tigers were amazing, but somehow seeing the real thing makes you realize try as we might, man can't improve on nature.
Most of the animals were away for the night, but they had some they were walking around the park for people to see like a porcupine and a couple of goats. Then in the tiger den one had decided to come right up the glass while we were there. It was amazing to see and I wish I had gotten a better picture but I was too caught up in the moment. I guess better to live the experience than be obsessed with snapping it. Still before it left I got this shot of it walking off.
Unfortunately I must have missed the sign explaining what Chinese myth this relates to, but this was my favorite display of the night. The beautiful winged whales, the vibrant colors and the way it all reflected in the mirror still water.
Being a lover of all things horse, Mackenzie wanted her picture take with anything even vaguely horse-like.
These are called Win Fish, fish with wings who make calls like mandarin ducks. They appear very rarely, but when they do it means a flood is soon to happen.
Chinese artists come over and hand make all of these, though to be fair some of them are reused year after year. Still the results are amazing and makes you think about what a world we live in. These artists from a country we are rivals with, sharing their culture and showing we can all get along.
We bundled up and hit Zoolumination 2022 at the Nashville Zoo. We hadn't been since 2019. It was fun back then but this year was much better.
Not knowing if she will be able to come back for Christmas (and wanting to keep her busy) we decided we'd decorate for Christmas a little early so Mackenzie could get the full Greer House At Christmas experience (TM). Let the unboxing begin!
It takes a village to keep an energetic four year old entertained, with pitching in from Great Grandpa Gene.
Mackenzie is here to stay the week, dropped off by her Mom and culminating in a slightly delayed Thanksgiving when her Dad and Payton come up next weekend.
We attended another drinks with dems event. This was was better, you could hear people, but mostly it was better because we did so well in the midterms! Not in Tennessee of course which is turning into an ever redder political cesspit. But hey, we'll take what joy we can in the good results for the rest of the country.
What a great trip. We ended up spending almost 5 hours at the museum. I had looked forward to seeing a Blackbird and of course Dad's Hexagon system, but I really enjoyed every bit of the museum from hanger to hanger, seeing the evolution of flight from sticks to space. Well worth every moment of the journey and getting to spend time with Dad!
It was incredibly satisfying and really cool to be able to see in person something I had heard so many stories about. To see the parts and how they worked, the physical construction of the satellite, even the airplane that caught the buckets shot back to earth.
Here is a breakdown of one of the pods, starting with the ablative shield, then the gold shield, then the actual pod that contains the film and ending with the rocket that would guide it down to earth.
Again for ease of reading and posterity the sign says:
Hexagon KH-9 reconnaissance satellites featured four recovery vehicles or "buckets" that dropped back to earth from orbit carrying exposed reconnaissance camera film for processing. A mapping camera attached for some missions at the front of the satellite added a fifth, smaller bucket. US Air Force aircraft snatched the parachuting buckets in midair over the Pacific Ocean near Hawaii.
Hexagon film return buckets had to be maneuverable, vacuum-sealed, temperature controlled, lightweight, strong, and recoverable. Once ejected from the Hexagon vehicle, a small retro-rocket slowed the vehicles for atmospheric re-entry, with smaller thrusters providing, and then slowing a stabilizing spin.
The outer cover of high-temperature resin charred away to carry off heat during re-entry. Another thermal cover, plus an array of thermostats and sensors kept the film at the correct temperature in space and during descent. Once the vehicle reached about 50,000 feet, parachutes slowed its decent. Battery-operated radio signal emitters helped aircraft locate the buckets, which could float if they landed in the ocean. McDonnell-Douglas built the KH-9s Mark 8 recovery vehicles, white General Electric made the mapping camera's smaller Mark V vehicles.
Technical Notes
Film load: 52,000 to 77,500 fee of film maximum per vehicle.
Film weight: 500 lbs maximum per vehicle
Vehicle weight: 956 lbs.
The maneuvering thruster on the back of the satellite to change course and keep it in orbit, complete with Dad explaining some machination of how it worked.
Here are the two giant cameras, one facing forward and one back to create huge panoramic pictures with details on objects as small as two feet across. Amazing for the time and that these were physical cameras, taking snapshots onto film. hard to imagine in today's digital world, but back then it was cutting edge. The silver balls had helium in them to aid the film train. The film was moving very fast and was very thin so the helium helped keep it light and moving without snapping. An extra precaution because if that happened, there was no fixing it.
Here you can see the films pods and how they would have been attached beneath the satellite. The white one has the full ablative shielding as it would have appeared in space. The gold is an example of the layer beneath the ablative one, also for heat control and protection. There were four of these buckets and when one filled up it would be shot down to earth and grabbed by the previously mentioned Satellite Catcher.
Information about the project and the satellite. For ease of reading and posterity here is what it says:
HEXAGON KH-9 reconnaissance satellites were the largest and last U.S. intelligence satellites to return photographic film to earth. During the Cold War, 19 HEXAGON missions imaged 877 million square miles of the Earth’s surface between 1971-1986.
HEXAGON’s main purpose was wide-area search. Analysts pored over HEXAGON’s photos of large areas, then focused in on potential threats with close-up surveillance from GAMBIT satellites.
The Lockheed Corp. built the HEXAGON vehicle. Its development included creating a very complex camera and film system. The satellite featured two separate cameras, designated KH-9 and made by the Perkin-Elmer Corp., working together to produce stereo images. These so-called “optical bar cameras” on the bottom of the satellite spun on their axes, taking overlapping images to form a very large panoramic picture. Objects smaller than two feet across could be imaged from around 80-100 miles altitude.
Some missions included a separate mapping camera mounted at the front of the satellite. This camera imaged wider areas to make very accurate maps for war planning and featured its own bucket-like film return vehicle.
The U.S. Air Force launched HEXAGON satellites aboard Titan IIID rockets from Vandenberg AFB, California, and provided tracking and control at an Air Force facility at Sunnyvale, Calif. USAF aircraft recovered film return vehicles in midair near Hawaii.

Finally, tucked away in the last corner, the real reason we came to the Museum. The project Dad led, the satellite he built and put into space, the KH-9. The only downer was they used ot have a KH-8 on display too, but had recently moved it to storage to make room for a new space exhibit. Still, here it was, the object of so much family history and stories.
