We got our compass out, we aligned the radar to north, and we were done. You don't realize anything exists like this until you get the job. Servicing an unmanned aerostat makes for some interesting ground duty. Imagine an entire aircraft darting about the tarmac in the slightest wind, like a greased weather vane. To control this darting, the balloon's nose rotates on a mooring tower, and the rear wags with brute force on a custom-curved steel monorail.
People enter the aerostat through what is essentially a large black cloth bag.
To climb onboard, technicians snub the rambunctious radar flyer with strategically laced ropes, like the little Lilliputians who worked on Gulliver. Inside, a technician checks the radar payload. Her work compartment is sealed from the helium hull. If not, she would speak in a squeaky soprano voice. Like most technicians, she carries a respirator pack, radios and a knife.
