arly model original "Speedway Pacemarker" tether car powered by a Hornet .60 ignition engine. The Pacemaker was designed by Joe Olender of Indianapolis, IN. Joe wanted to introduce a semi-custom car for the racer who wanted to be competitive without having to build a light weight car from scratch. Joe commissioned The Standard Machine Works out of Indy to produce the car in 1947. To achieve light weight, the car featured a magnesium pan, a laminated Bakelite body and Bakelite rear wheel bearing covers. The Pacemaker came fully equipped with tail skid, tether brackets, coil with Bakelite mount, condenser, switch, fuel tank, bridle and battery strap. The two most unique features of the Pacemaker other than its light weight construction, are the "air-ram" special fuel tank and the extra long crankshaft for the Hornet and McCoy engines to accommodate the special flywheel and pinion gear. There were two versions of the Pacemaker, the early models have a brass bowed grille, later model featured a slotted sheet aluminum grille. There were 150 of the Speedway Pacemaker produced which does not make the car extremely rare but this particular car is a complete unmolested correct survivor. It appears the car has been run. Nothing has been clean up. Completely wired. Tires are still pliable. The hand painted numbers and graphics are starting to show ware. Overall length is 15 7/8", wheelbase is 10 3/8", track is 5 1/4". Pretty darn nice car for being around for 63 years.

Mayukh Nath, Computer Engineering Undergraduate Student inspects the upper unit on the Mi-TEE (Miniature Tether Electrodynamics Experiment) cubesat inside a CLaSP laboratory on North Campus in Ann Arbor, MI. before it launches into Earth's Ionosphere.
The space mission being planned by multiple student teams composed of undergraduate, Master’s, and doctoral students at the University of Michigan will test miniature electrodynamic tethers as a propulsion concept for small satellites.
The potential of the platform is tremendous: the low cost of launching satellites like picosats and femtosats into orbit due to their low mass and small size enables new paradigms for space missions using large numbers of spacecraft. Coordinated fleets of these satellites could provide the ability to perform simultaneous, multi-point sensing and rapid re-measurement of a single location.

On March 6, 2017, FDNY launched its first ever tethered drone to respond to a fire in a 6-story building on Crotona Park North in the Bronx.
The $85,000 FDNY tethered drone weighs 8 pounds and incorporates both a high-definition camera and infrared camera. These capabilities allow the drone to transmit live images of a fire operation to the Chief in charge of the incident. The drone’s camera allows Chiefs at the command post to see where Firefighters are operating on the roof of a building and to make decisions to help suppress the fire and keep FDNY members safe. The image is fed directly to the Incident Commander and is also shared with senior decision makers in the Fire Department through the FDNY Operations Center.
"We deployed the drone for the first time in support of a 4th alarm fire in the Bronx,” says FDNY Director of FDNY Operations Center, Timothy Herlocker. “We were able to get a good view of the roof, which allowed the Incident Commander on the ground to view the Firefighters as they were conducting roof operations, venting the roof and putting water on the fire."
“This fire was helped by our drone, said Deputy Assistant Chief Dan Donoghue, the incident commander at the 4th alarm fire. “The roof started to fail and we had a lot of great radio reports but that’s only verbal, so with the drone we had good visual pictures and it really helped us make decisions to put this fire out and keep our members safe.”
The FDNY drone is tethered using a small cable that carries electricity up to the device, which gives the drone an unlimited flight time. The drone can stay aloft for as long as necessary to keep an aerial view on the target. All controls, data, and power transmit back and forth through the tether preventing interference with radio frequency signals. The drone is piloted by specially trained FDNY Firefighters from the Department’s Command Tactical Unit. The Department currently has three drones in its fleet to deploy as needed.
“This new technology is going to make a positive impact in our fire operations,” said Fire Commissioner Daniel A. Nigro. “The drone’s camera gives our Chiefs a view they never had before. It’s an important tool that will make our members, and the people we protect, even safer.”
FDNY works closely with the FAA to ensure the drone operates safely and adheres to all rules and policies regarding airspace in New York City. The Fire Department Operations Center contacts the FAA prior to flying the drone for permission to deploy at night, or into FAA Class B Air Space - the FAA’s most restricted air space. Approval takes approximately ten minutes and takes place while the drone and its operators are responding to a fire.

The tether line is attached first so the balloon can’t escape; then the balloon is inflated with helium gas.
A helium-filled balloon is used to lift a still-photo camera to an altitude of approximately 300 feet. The balloon is tethered, and an operator on the ground walks the balloon across shallow seagrass beds or uses a slow-moving boat in deeper water to photograph seagrass beds and bay bottom habitats. The technique is not limited to seagrass beds and is useful in any habitat in estuaries, lakes or on land where fine-scale imagery is needed. Because the balloon is tethered, however, it is not useful in forested areas!

Aerostat seen from Ramsey Canyon, AZ
This surveillance blimp is one of eight aerostats deployed along the U.S. southern border. The other blimps are located in Texas, New Mexico, the Florida Keys, Puerto Rico, and Yuma, Arizona. The first site was built at High Rock, Grand Bahamas Island, in 1984. The second site was built at Fort Huachuca, Az, in 1986. About 25 to 30 people are employed at each of the eight aerostat sites.
en.wikipedia.org/wiki/Tethered_Aerostat_Radar_System
The aerostats are large fabric envelopes filled with helium, and can rise up to an altitude of 15,000 feet (4,600 m) while tethered by a single cable. The largest lifts a 1000 kg payload to an operating altitude providing low-level, downward-looking radar coverage. The aerostat consists of four major parts or assemblies: the hull and fin, windscreen and radar platform, airborne power generator, and rigging and tether.
The hull of the aerostat contains two parts separated by a gas-tight fabric partition. The upper chamber is filled with helium and provides the aerostat's lifting capability. The lower chamber of the hull is a pressurized air compartment. The hull is constructed of a lightweight polyurethane-coated Tedlar fabric. An airborne engine drives the generator, supplied by a 100-gallon diesel fuel tank.
The aerostats have proven to be a fair weather friend. They must be brought to ground in high winds.
TARS surveillance data is used by Customs and Border Protection and by the Joint Interagency Task Force-South in support of border security and counter-drug operations.
According to one study in 2012, the aerostat at Fort Huachuca helped Border Patrol agents make almost 100 arrests in Arizona.
Using radar they continuously scan the area along the border, looking for low-flying aircraft drug smugglers use to bring drugs into the United States. The sensors on board can detect activity in distances of up to 230 miles.
TARS has been operated by the U.S. Air Force, but the Department of Homeland Security picked up the project and its funding for fiscal year 2014.
The 1928 Ford Model A was a typical donor car for the development of the early Harry Miller Race cars. Such items included the steering box, axles, differential, springs, and the transmission; although most were highly modified for racing.
In this model, the miniature Offy engine was scaled from drawings of the full-size engine and sports Ron’s custom made Winfield carburetors. Ron says it runs best on E-85 Ethanol and spark ignition. Stainless steel was used to fabricate almost everything except the engine, transmission, differential, rims, and body. The model has functional gauges, pedals for the accelerator and brakes, shift lever for forward and reverse, and an external hand brake. The hand pump pressurizes the fuel tank that is located behind the driver’s seat and the lubrication is via dry sump with the oil tank located between the driver and engine. Also it is equipped with steering, leaf spring suspension, friction shocks, and Ron’s custom-made spoke and splined knockoff wheels
Ron built this model as a tribute to his Father who owned and raced the full-size car in the mid 1920s. It is almost exact- even down to the numbers and lettering on the body. Except for the engine Ron fabricated everything from memory and a few family photos of his Dad’s race car. This model measures 32 inches long, 16 inches wide, 13 inches high, and weighs 25 pounds.

There are many aspects to creating a successful piece of work. It's not just the image, it's the text, the layout, the order, it all adds up to making something explode or fizzle. This is my first real foray into trying to put together a series, a story if you will, of this kind.
Ben Mcdonnell, who own Famous Policy, also races him. Originally I was going to come at this with a fashion bent, but after a couple minutes of shooting I realized the true story lay in the connection between these two animals. The best photos were caught when neither of them were paying any attention to me. In those moments, it was like I was peering in on a couples private conversation. The stories, the experiences, the hardships…experienced between these two… it was fun to try and capture.

Each cat has had his turn at making him stop
So far none have managed to reach the damned spot.
Please Jeffers, understand we've all reached the end
of our tethers and soon we will all choose to send
you back to you're breeder and now thats the end.
