In the early days, the state of Utah used to stock lakes with fish by hauling small fish in <a href="https://wildlife.utah.gov/news/wildlife-blog/188-extreme-fish-stocking.html" class="on">metal milk cans on horseback</a>, then by off-road vehicles and trucks.

In this <a href="https://www.facebook.com/UtahDWR/videos/1494993280849050/" class="on">Facebook post</a>, Utah Division of Wildlife Resources posted a video clip of how 200 high-elevation lakes across the state were stocked with fish. They noted that these lakes weren't easily accessible by vehicle, so air drop of fish is the preferred method.The fish dropped were between 1 to 3 inches long, so they "flutter down" slowly to the water.An airplane can hold hundreds of pounds of water and 35,000 fish in a single flight without reloading.#fish #aerialfishstocking #wildlife #horse #Utah

Aerial Fish Stocking: Utah Restocked Lakes by Dropping Thousands of Fish From an Airplane

You might have seen <a href="https://www.bostondynamics.com/spot" class="on">Spot</a>, the robot dog developed by Boston Dynamics. But did you know that the cute (well, relatively cute) bot actually had much creepy precursors named the <a href="https://en.wikipedia.org/wiki/BigDog" class="on">BigDog</a> and the <a href="https://en.wikipedia.org/wiki/Legged_Squad_Support_System" class="on">Legged Squad Support System</a> (LS3) robots.The DARPA-funded LS3 was to function as a pack mule, able to carry 400 lb (180 kg) of equipment for a squad of marines and travel a distance of 20 miles without refueling. And thus, Boston Dynamics built it in the approximate shape and size of a horse.The LS3 responded to voice commands, including those to autonomously follow a human controller along a path. During a training exercise, one marine company nicknamed their robot, "Cujo" and noted that the robot could reach places difficult to reach by all-terrain vehicles. When the robot fell over due to steep hills, it was able to right itself most of the time.In 2015, the Marines discontinued the LS3 program, because the gas-powered robot was too loud for stealthy movements, and that it would be difficult to repair in the fields.#robot #LS3 #horse #BostonDynamics #DARPA #militaryequipment #logistics
