The 71 meter long Aerostat, moored, and most of the site buildings all in one pic. Castle Dome is in the backgroound, a sure way to tell it's the Yuma baloon

Launching the Aerostat late one afternoon. Too hot usually to do it in the middle of the day, due to thermals that would bang the aerostat around badly. That's Tony walking around. Great guy, one of our mechanics.

Just hit the mooring tower with the nose probe at sunset. Next we pin the mooring lines and then we walk away to do maintennance, eat dinner etc. The main winch motor, a huge Cat diesel is inside the mooring system
I was a Flight Director, later on after the Bob Edwards period and we stood up operationally, on the Tethered Aerostat Radar System (Yuma TARS). I was also the lead Electronics Tech. They were a pretty cheap company that ran the thing. Saved a ton by having me on both jobs.
Just so happened I was on duty the night we broke the coninuous time aloft record of over 31 days. Stayed up another 2 days to set it in stone, then had to pull it down, since helium leaks no matter what. Run outta helium, it no go UP no mo!
The small (relatively) bulge underneath is where the radar system hung and spun. The entire Radar system, including the huge, Kevlar based antenna, rotated. We could see out to 160NMi. It was to provide surveillance of our sector, looking DOWN to see the drug smugglers, etc trying to sneak in under all the ground based Radar systems. To give a perspective on size, we could comfortably fit 3 people on the Radar's maintennance platform. There is a hatch in the bottom center to provide access to the radar.
The tether, that held the Aerostat to the mooring system and gave us altitude control to the foot, was made of woven kevlar strands, all about 1" in diameter. Had the electric Power run up 3 8Ga wires in the center. About 10KvA. Breaking strength tested out to 70,000 lbs pull. Every 6 months we cut off about 200' worth, reterminated, and reattatched, for testing break strength. Total process, 24 hours. Takes a bit to properly reweave the kevlar into a loop for attachment to the Aerostat. Took us 8 hours alone to properly reterminate the electrics run up the center alone.
90% of our time was spent watching it sit up in the sky and do radar stuff. The radar data was sent to March AFB for interpertation and action, as needed. We had full telemetry on the Aerostat and radar, and could monitor the data sent to March.
We monitored the aerostat telemtery 24/7/365, and had a crew on duty 24/7/365 for launch or recovery ops as needed.
Any questions, please feel free to google them
I think i got finger cramps now!
