EN Otto Lilienthal: "FIRST IN FLIGHT" - 7 Seconds for Eternity

[@richard_loosemore]

As a 15-year-old I tried to build a glider for myself, after falling in love with Lilienthal’s design. I built it using an old shop awning lashed to a crude wooden frame, then tested it by running down the hill behind our cottage in Peasmarsh (Paul and Linda McCartney lived at the top of that hill, in fact). The thing actually took off! I had a split second to decide whether to keep going up point the nose down and crash. I opted to crash. Broke my ankle and was off school for two weeks. But I probably saved my life.

[@m.i.c.h.o]

Wow! How big was the hill? I wouldn't think that would be life or death...

[@bernardorodrigues6410]

Wow. Congrats on your build man. Will you build a better version?

[@michaelboyko5024]

Respected, sir! Was after your flight McCartney wrote his song "Distractions like butterflys are puzzling over my head"?

[@riazhassan6570]

I was fifteen when I jumped off a high wall with a wing-like contraption made of bamboo poles and old sheets. I landed with a tangled thump on soft dirt. Luckily, nothing broke except the wing. Thereafter I ventured a powered gyroplane somewhat like the ones that submarines towed in WW2, with welded steel tubes and an old motorcycle engine. Luckily, it lurched to one side and shook itself to death on the very first attempt to move. Some kind of alarm must have entered my obtuse teenage brain, because I never tried anything bigger than models afterwards

[@captainjj7184]

Bought several aluminum pipes with months of saved school lunch money to build my own glider but then my dad used 'em all up to fix the house windows. Fast forward, waay forward, last month in fact, I decided to jump off a ledge in an attempt to float down with the biggest umbrella I've ever bought. The thing collapsed into an inverted dart tumbling me into the asphalt road - luckily no broken bones, just crying in pain. My daughter who was filming was cracking up unstoppably. Congrats man, you went ahead and actually did it. You might not want to try again, but as for me, I haven't used up my turn yet, so... wish me luck for my next, real big try!

Wilbur Wright was always respectful and appreciative of the great accomplishments of Otto Lilienthal. The video is a great tribute to a great man.

[@michaelladigo2395]

Yes, but the Wrights ended up re-doing all of Lilienthal's tables and concepts of lift in order to achieve actual powered, controlled, and continuous flight. Lilienthal's "flights" were mere semi-controlled descents down a hill. Weight-shift is not truly a proper means of control and is what inevitably what killed him. Wrights were "First In Flight". Sorry.

[@jonnyolson4387]

@@michaelladigo2395 The Wrights achieved mechanical directional control first, but Lilienthal was the first to fly in a controlled manner: A weight shift hang glider is FLYING. Hundreds of powered weight shift airplanes fly everyday. The Wright Brothers conclusions on airfoil design were incorrect because their wind tunnel was using airfoils that were too short and the air was moving too slowly. The Reynolds number (chord, speed, density, viscosity ) was way off and the Wrights airfoil was far from the correct shape for the speed they were going and the chord length of the wing. Their incorrect airfoils were detrimentally used by the US up threw WW1. The correctly shaped 2 surface wings of Fokker and German wind tunnel data finally proved how wrong the Wrights were.

Thank you for this important reseach in aviation history. Otto was even the first hang glider pilot, flying 83 years before me. We were very aware of Otto as our historical reference at that time 1974. Bill Moyes and Bill Bennett was the new pioneers in hang gliding 1969. Flying with weight shifting as the only control have it's risks, because if you enter a strong downwind you lose your weight and subsequently ability to steer. I guess that was what ended Otto's life, as it almost did with my, more than once.

You would have thought they would have used an experienced hang glider pilot to test fly it, after all it is obviously a weight shift controlled glider. Personally I would have stiffened up the tail somehow to make it safer for outdoor flying. Going from the drawings alone we can't really know how stiff Lilienthal's original structure was.

He died in 1896. There was no glider expert, aviation was not invented yet.

I too had a fascination for flight from an early age. By 1976 Hang - gliding had arrived in Britain and at 30 years of age this was my introduction to real natural un-powered flight from the beautiful coastal resort of Rhossily on the Gower coast of Wales . After my first two seater flight on a seated Highway glider with an instructor. After a top to bottom flight from 600ft I was HOOKED! My last flight was on a second hand Highway Demon glider from Merthyr Common in 1989 , my longest flight being 3Hrs. Later at the tender age of 6o I was able to obtain a NPPL licence flying a Cessna 150 , but regard my time on Hang-gliders the most exiting and natural way to fly .

[@brianperry]

Over fifty years ago I made a glider from old charts....I was on a ship in the south Atlantic...It wasn't particular scientific although I did understand the principal of having a curved wing, for lift. The main spar was tightly rolled and glued paper with the wing shape formed over it, it was about 1.5 metre wing span, The fuselage was formed in a similar fashion to the wing spar. The tail was formed in a similar fashion. I had to guess, educated guess, at the centre of gravity....When all was finished I sneaked it to the bridge whilst on watch with the Mate. It was a relatively calm, but a heavy rolling swell running. We stood on the wing of the bridge..... and launched my creation into a fifteen knot head wind created by the ship. The glider soared upwards then rolled towards the waves then to our surprise it skimmed the water like an Albatros. Its total flight time was between 10-15 seconds before it alight on the water ...and was gone...Watching this video of a pioneer of flight returned me to that day so long ago...

[@saucerguy3]

I brought the plans for this glider to Home Depot. I went to the pvc/plumbing, plastic sheeting section, and the rope department and asked for help, their staff looked at the plans in each area, then me, and walked away. I was blocked from access to the duct tape isle and they confiscated my Home Depot charge card, mumbling something about liability and insurance risks and someone even mentioned needing mental evaluations... Thank you Otto, won't be making that mistake any more, next time will shop at Walmart, you should have warned us!

[@travelbugse2829]

Many thanks. Absolutely fascinating to watch. Lilienthal was truly the father of hang-gliding. I know that people are saying the ancient Chinese invented flight, but we do not have sufficient information about their machines. I should be patriotic and say that George Cayley in the UK created a primitive glider in the early 1850s. Later in the 1890s, another Englishman Percy Pilcher visited Lilienthal several times and was inspired by him, flying similar machines. Pilcher died back home after an in-flight structural failure in 1899. My thoughts as an ex-weight shift pilot: The tailplane should have been more controllable. I believe the high relative angle of incidence between the wing and the tailplane/stabiliser would keep the aircraft stable only within a narrow speed range. It was stable as set up, but diving/gaining speed would produce a rapid automatic nose-up correction that would keep the pilot very busy! It would have been a 'phugoid flyer' if flown long distance, I believe. That is not to dismiss any of the pioneering work that Lilienthal made, however - an amazing, talented person who gave his life for scientific progress.

"Was it a fault in the material or was it a constructional defect?" I believe the idea that the storks don't flap their wings does not mean that their wings are rigid/fixed. Even in the video of the flying stork, a close observation reveals the wings are flexing, bending, turning, twisting. While it's subtle from a distance away, the wings are far from just randomly flexing from wind/loads. Hence, the major flaw in the assumption that it can be duplicated with a flexible model. None -the-less, He deserves the recognition and all the world-wide credit for his historical achievement!!

Very nice. I studied Otto Liliethal at school 50 years ago and very much wanted to build and fly my own glider, but didn't. He built an artificial hill 15 m (50 feet) high as he lived in a flat area with no suitable hills to launch from and I often admired the amount of work that would have taken.

In order to reduce the total weight of the aircraft, all bamboo rounded by rope will make it durable and is to be used instead of wooden rod in modification. A vertical enclosed bamboo loop is also to be installed and tied in the front part of the aircraft as the support for airman's feet and used as a step for his up and down jumping movement and such movement is similar to add energy to the wings during flying. No energy to be transferred to wings movement won't fly longer. Moreover, an additional of two parachutes to be installed at the left and right wings which would be opened after flying to increase uplift forces when required. I think that it will fly longer and land safely after modification.

This project was carried out with typical German precision, and they clearly got to understand how the Lilienthal flying machine worked. But as a Hang Glider pilot from the very beggining , I know that trying to judge the flying characteristics of a glider like this on FLAT earth will not work very well. This type of flying machine needs the air to have a componant of rising up to meet the machine, as one has when flying it from a hill top. In their wind tunnel, the air was coming AT them, not UP to them and this is very important. When you stand on the top of a hill, you can feel the air coming up under you and all you need to do is take a couple of steps and the glider lifts up. Then you move you weight forwards, and the machine lowers its nose and moves forward, but because of the rising air the machine, also rises. This is exactly why the Lilienthal glider flew so successfully and is also the exact same way that modern day Hang Gliders fly. Otto was in essence the very first Hang Glider Pilot in the world!!

[@MichaelMcFearin]

[@1DesertPirate]

Building Lilienthal's glider from his own design using original as could be gathered and made materials was a fascinating and historical project. I wonder who of these scientists, aeronautical engineers and builders ever read or saw anything of the Wills brothers in southern California. The Wills brothers knew of Lilienthal and his glider, and built their own gliders from scratch and would up flying for miles and staying airborne for hours. They basically reinvented the hang glider and built up a successful, for a time, hang glider company. I bought a hang glider in 1974 and taking off into the air is a remarkable experience, one Otto did for the first time back in 1891. His insight into flight by watching storks fly overhead and studying a bird's wings is a seminal part of the history of flight.

Since man had flown a hundred years early, and higher up to 30,000 ft and longer; I dare say there are aircraft that did not rely on Lilienthals insights. It was only 3 years later that the first Zeppline was built and flew several miles in 1900.

It appears from the wind tunnel tests that the pilot sits right at the center of pressure, or even behind, rendering it unstable unless he pulls his weight forward slightly, moving his weight, and the center of gravity, slightly ahead of the center of pressure, making it stable and controllable.

I agree Lidmark; but if you look at the title they say "first in flight" Also it appears by their video that really this glider was incapable of being launched without a head wind and may not have had enough lift even then to lift a normal size human into equiliibrium ; ie it would immediatley start to decend even going 50 kph. I think he understood the principles - thats true; and perhaps if he didn't die he would have built a real glider that actually flew without a head wind and might actually rise without having to go 50 Kph.

I live right near Sand City, wish I would have known, definitely would have watched this!

[@Andrew-13579]

They had this glider in California. I wonder if they had given thought to flying it off the cliff at Torrey Pines, CA.

[@tolitsdterrible4785]

Have they considered the height and weight of Lilienthal? I believed he designed the glider's wing size and strength based on his own body statistics.

[@tohaason]

Good point. The pilot in the video is a big guy (though slim). I'm thinking that an actual hangglider pilot of shorter lighter stature would be a better match than a tall airplane pilot?

[@davidwrobel8089]

Basically the first successful glider, this can't be taken away from Mr Otto, Fast forward to the Wright Brother to get it right

First in flight of any kind (hot air balloon): Jean Pilatre de Rozier First in unpowered heavier than air flight: Otto Lilienthal First in powered heavier than air flight: Orville Wright The Wright brothers flew unpowered heavier than air gliders successfully for years prior to their first successful powered flight. Blimps and Rigid Airships flew from 1852 to the present with a variety of accomplishments during that time. Filled the gap in the time between hot air balloons and the Wrights first powered flight.

The first to fly hot air ballons were Montgolfier brothers and a brazilian father Bartolomeu de Gusmao with public assistance ...

Your film makes it sound like Otto crashed on his first flight. Otto Lilienthal flew gliders about two thousand times over a period of five years before his fatal flight.

[@tedmoss]

No one said that.

It is very possible to crash without being killed. I did many times using a hang glider and once in my plane.

Yes ,but in 1894 Lawrence Hargraves flew his Box kite designs at Stanwell Tops, Sth of Sydney Australia. These designs which the Wright brothers, who had been in correspondence with were the designs they adopted. Credit due, but often Hargraves work is forgotten.

[@huto9606]

[@altamiradorable]

Everybody talks about the Wright brothers but never give enough credit to Otto Lilienthal !

[@EpicureanHikers]

They did. And Cayley

[@matthewkeeley4479]

Viewing the few photos I've seen of Otto's flights, he was seated if you will, in a waist sling. The required excess strength, needed without a stable seat, would draw too much attention to aright the aircraft. A seated pilot, exercising the center of gravity by weight shift, would have a better chance of longer flight times.

[@redliv]

That was beautiful, I wonder if they can make another one using modern materials and technology applied

[@zackworrell]

The Wright Brothers were inspired by him and credited him for his discoveries, but they abandoned his technical research in exchange for their own achieved using a custom built wind tunnel. The wright brother are the first in sustained powered flight.

Sir George Caley in Yorkshire England flew his first model Glider in 1804 and a successful flight was made in a manned Glider with his footman as Pilot in 1853. This was the first Glider flight useing the understanding the principles of Weight,Thrust,Drag and Lift in the design which he discovered and recorded . The Wright Brothers used those principles in their design in the first powered flight,NASA accept Caley as the Father of Aviation as he was the first to understand the principles of flight.

[@JoeOvercoat]

The updraft on those dunes is substantial, to say the least. I was surprised at how steep the glide slope was, given that.

[@colinschaeffer3940]

The steep grade is the only way Lilienthal could "fly".

[@sailorman8668]

The glider has a very poor glide ratio due to its inherently large level of drag and angle of attack. Even with updrafts, the glide ratio will never be outstanding.

[@Vincent-jw2wi]

i am thrilled by how satisfying this is

[@WarblesOnALot]

G'day. 2 words... Lawrence Hargraves. Lillienthal and Hargraves corresponded for years. My understanding is that Hargraves first determined that a curved ("Cambered") Surface generates far more "Lift" than does a Flat Plane Surface - at the same Angle Of Attack. He discovered this using Tethered Boxkites. The reason Lillienthal's Gliders flew..., was because he used Cambered Wings - and Hargraves taught Lillienthal (why) to use Cambered Wings. So... LAWRENCE HARGRAVES...! Such is life, Have a good one... Stay safe. ;-p Ciao !

[@David-oi7im]

... good job on your presentation..

[@davidstone2319]

I'm amazed at how many people don't grasp what Lilienthal did - so many here don't understand he was in control. Gliding is flying. When an eagle is soaring - is he not flying? Whoever said the wings need to be narrower and longer doesn't understand that such configuration would make it less controllable in a weight shifting glider. Was Lilienthal the first man to ride a glider? No. But Lilienthal rode a glider thousands of times, in public, and he inspired others - something that attempts before the 19th century didn't do.
