The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA's Hyper-X program developed in the late 1990s. It set several airspeed records for jet aircraft. The X-43 is the fastest jet-powered aircraft on record at approximately Mach 9.6.
Pegasus is an air-launched launch vehicle developed by Orbital Sciences Corporation (OSC) and now built and launched by Northrop Grumman. Pegasus is the world's first privately developed orbital launch vehicle. Capable of carrying small payloads of up to 443 kg (977 lb) into low Earth orbit, Pegasus first flew in 1990 and remains active as of 2021. The vehicle consists of three solid propellant stages and an optional monopropellant fourth stage. Pegasus is released from its carrier aircraft at approximately 12,000 m (39,000 ft), and its first stage has a wing and a tail to provide lift and altitude control while in the atmosphere. Notably, the first stage does not have a thrust vector control (TVC) system.
The Fox–Wisconsin Waterway is a waterway formed by the Fox and Wisconsin Rivers. First used by European settlers in 1673 during the expedition of Marquette & Joliet, it was one of the principal routes used by travelers between the Great Lakes and the Mississippi River until the completion of the Illinois and Michigan Canal in 1848 and the arrival of railroads. The western terminus of the Fox–Wisconsin Waterway was at the Mississippi at Prairie du Chien, Wisconsin. It continued up the Wisconsin River about 116 miles (187 km) until reaching Portage, Wisconsin. There travelers would portage to the Upper Fox River, or eventually, use the Portage Canal. It continued about 160 miles (260 km) down the Fox River, following it through Lake Winnebago and continuing on the Lower Fox over 170 feet of falls to the eastern terminus of Green Bay.
The Driftless Area, also known as Bluff Country and the Paleozoic Plateau, is a topographical and cultural region in the Midwestern United States that comprises southwestern Wisconsin, southeastern Minnesota, northeastern Iowa, and the extreme northwestern corner of Illinois. The Driftless Area is a USDA Level III Ecoregion: Ecoregion 52. The Driftless Area takes up a large portion of the Upper Midwest forest–savanna transition. The Blufflands refers to the eastern section of the Driftless area in Minnesota, due to the steep bluffs and cliffs around the river valleys. The western half is known as the Rochester Plateau, which is flatter than the Blufflands. The Coulee Region refers to the southwestern part of the Driftless Area in Wisconsin. It is named for its numerous ravines.
In the U.S. state of Wisconsin, the Central Plain is a geographical region consisting of about 13,000 square miles (34,000 km2) of land in a v-shaped belt across the center of the state. Beginning in the west, the Central Plain originates in Burnett and Polk Counties and runs southeast to Columbia County, where it turns northeast and reaches its end in Marinette County.
Lake Duluth was a proglacial lake that formed in the Lake Superior drainage basin as the Laurentide Ice Sheet retreated. The oldest existing shorelines were formed after retreat from the Greatlakean advance, sometime around 11,000 years B.P. Lake Duluth formed at the western end of the Lake Superior basin. Lake Duluth overflowed south through outlets in Minnesota and Wisconsin at an elevation of around 331 m above sea level.
The Pegasus Project was a NASA initiative to study the frequency of micrometeoroid impacts on spacecraft by means of a constellation of three satellites launched in 1965. All three Pegasus satellites were launched by Saturn I rockets, and remained connected with their upper stages.
HMS Pegasus was an aircraft carrier/seaplane carrier bought by the Royal Navy in 1917 during the First World War. She was laid down in 1914 by John Brown & Company of Clydebank, Scotland as Stockholm for the Great Eastern Railway Company, but construction was suspended at the start of the war. The ship was converted to operate a mix of wheeled aircraft from her forward flying-off deck and floatplanes that were lowered into the water. Pegasus spent the last year of the war supporting the Grand Fleet in the North Sea, but saw no combat. She spent most of 1919 and 1920 supporting British intervention against the Bolsheviks in North Russia and the Black Sea. The ship remained with the Mediterranean Fleet until 1924, but was placed in reserve in 1925 after a brief deployment to Singapore. Pegasus was sold for scrap in 1931.

The capture of the Caen canal and Orne river bridges was an operation by airborne forces of the British Army that took place in the early hours of 6 June 1944 as part of the Normandy landings of the Second World War. The objective was to capture intact two road bridges in Normandy across the River Orne and the Caen canal, providing the only exit eastwards for British forces from their landing on Sword Beach. Intelligence reports said both bridges were heavily defended by the Germans and wired for demolition. Once captured, the bridges had to be held against any counter-attack, until the assault force was relieved by commandos and other infantry advancing from the landing beach.
The Scaled Composites Model 351 Stratolaunch or Roc is an aircraft built by Scaled Composites for Stratolaunch Systems to carry air-launch-to-orbit (ALTO) rockets, and subsequently repurposed to offer air launch hypersonic flight testing after a change of ownership. It was announced in December 2011, rolled out in May 2017, and flew for the first time on April 13, 2019, shortly after the death of founder Paul Allen. The aircraft features a twin-fuselage design and the longest wingspan ever flown, at 385 feet (117 m), surpassing the Hughes H-4 Hercules "Spruce Goose" flying boat of 321 feet (98 m). The Stratolaunch is intended to carry a 550,000-pound (250 t) payload and has a 1,300,000-pound (590 t) maximum takeoff weight.
Pegasus Peak, at 11,736 feet (3,577 m) above sea level is the tenth highest peak in the Pioneer Mountains of Idaho. The peak is located in Salmon-Challis National Forest and Custer County. It is the 29th highest peak in Idaho and about 1.4 mi (2.3 km) north of Altair Peak.

On January 7, 2019, the wreck of Selah Chamberlain was listed on the National Register of Historic Places, and was given the reference number 100003288. She was the first shipwreck listed on the National Register of Historic Places in 2019.
The SS Francis Hinton was a wooden-hulled steam barge that sank in a gale off the coast of Manitowoc, Wisconsin, on Lake Michigan in 1909 while heavily laden with a cargo of lumber. On December 16, 1996, the wreck of the Francis Hinton was listed on the National Register of Historic Places.
Thomas Friant was a wooden-hulled ferry that served on the Great Lakes from her construction in 1884 to her sinking in 1924. In January 1924, while gillnetting out of Two Harbors, Minnesota in Lake Superior, she was holed by ice, and sank with no fatalities. In 2004 her wreck was discovered in over 300 feet (91 m) of water in pristine condition. The wreck of Thomas Friant was listed on the National Register of Historic Places in 2019.
