'''''Pre-Wright Brothers Flights''''' is the caption under which the video catalog of [[Molecular Reality Corporation]] lists a recording of one of the earliest [[sliding occlusion]] experiments of [[demonpore, inc.]] The catalog dates the recording to about 2015 or 2016 and says that the current was read out on a benchtop picoammeter.<ref name="records" /> On the company's YouTube channel the same video, 19 minutes 17 seconds long, is titled '''"best pore data yet"'''.<ref name="vid" />

The poster frame shows a corner of a bench in low light. Metal posts and a stage stand at the left, and a monitor above the middle of the frame glows orange. Below the monitor a benchtop meter with a red digital display reads -0.50. In front of the meter is a controller with a large knob and a small screen that lists X, Y and Z coordinates, and a hand points at the knob. On top of the controller sits a green felt figure with two fangs that resembles the company's mascot, [[Keltar]].<ref name="vid" />

All the parts of a sliding-occlusion measurement are in the picture, in the order of the signal. A positioner moves one surface across another, so that the opening between them widens, narrows or closes. A fixed voltage drives ions through the opening, and a picoammeter reads the current. A picoampere is a million-millionth of an ampere, about 6.2 million elementary charges per second.{{efn|1=One picoampere is 10<sup>-12</sup> coulomb per second and one elementary charge is 1.602 × 10<sup>-19</sup> coulomb, so the current is 10<sup>-12</sup> / (1.602 × 10<sup>-19</sup>) = 6.24 × 10<sup>6</sup> charges per second.}} The catalog says the current was "read out", and the display in the frame is the readout: one number at a time on a screen. About ten years later the company's streams recorded 200,000 samples per second from an [[EDR4]] amplifier.<ref name="records" />

The experiments came before the patent application for the method, whose priority date is May 9, 2017.<ref name="patent" />

The video has two names. The company's list of its videos calls it "Pre-Wright Brothers Flights", and YouTube shows "best pore data yet".<ref name="records" /><ref name="vid" /> The catalog's name takes its reference point from the history of aviation.

By December 17, 1903, when the Wright brothers flew at Kitty Hawk, North Carolina, people had left the ground in gliders for more than a decade. Otto Lilienthal made close to 2,000 brief flights in 16 designs between 1891 and 1896.<ref name="lilienthal">{{cite web |url=https://si.edu/object/lilienthal-glider:nasm_A19060001000 |title=Lilienthal Glider |publisher=National Air and Space Museum |access-date=2026-10-25}}</ref> He steered by shifting his body weight.<ref name="flyer" /> The Wrights, prompted by his fatal crash, used aerodynamic balance instead: wing tips that could be twisted to bank, a forward surface for climb and descent, and a movable vertical tail.<ref name="flyer">{{cite web |url=https://airandspace.si.edu/collection-objects/1903-wright-flyer/nasm_A19610048000 |title=1903 Wright Flyer |publisher=National Air and Space Museum |access-date=2026-10-25}}</ref> Their first powered flight lasted 12 seconds and covered 36 meters (120 feet). The longest of the four that day, by Wilbur Wright, covered 255.6 meters (852 feet) in 59 seconds.<ref name="flyer" />

The company uses the Wrights as a scale for its own hardware. Its catalog describes a second video, "nanotech history, in my mom's basement, March 2017", as footage of early mechanical nanopore "Wright Brothers" hardware experiments.<ref name="records" /> The experiments of the first video, in 2015 and 2016, came before that hardware.
