Re: What is a "hang glider" ?

There are gliders and there are parachutes.
You can ride inside a glider.
You can hang under a glider.
I call that a hang glider.
When you fly a hang glider, I call it hang gliding.
There are different kinds of hang gliders.
Some can stay up.
I call that soaring a hang glider.
I call the person who does that a hang glider pilot.

You can't ride inside a parachute.
You have to hang under it.
But nobody calls it a hang parachute.
When you fly a parachute, I call that parachuting.
There are different kinds of parachutes.
Some can stay up.
I call that soaring a parachute.
I call the person who does that a soaring parachutist.

NASA called an early Rogallo a "paraglider."
It was actually a hang glider - as established by definitions set even before the turn of the century.
That started a problem with labels.
It was a governmental screw-up that created an inaccurate technical language that migrated into popular vernacular.
But I don't have to buy into it.
In fact, I reject it.

Any questions?

Joe, you have spent a lot of time on forums explaining the language of NASA's mistake in a struggle to make it meaningful.
I wonder if there were any disagreements with those inaccurate labels, early on?

Part of a strong root of the word game arrived from Woglom in 1896 formally publishing a major treatise where he titled the book "Parakites". And he strongly defined the special kites without tails as "parakites".

===============================
NASA easily went to
"paraglider" for the tailless gliders
https://www.nasa.gov/centers/armstrong/multimedia/imagegallery/Paresev/index.html

======================================
A different river of "para" followed parachute
parachute (n.) Look up parachute at Dictionary.com
1784 (the year the use of one first was attempted, in Paris), from French parachute, literally "that which protects against a fall," hybrid coined by French aeronaut François Blanchard (1753-1809) from para- "defense against" (see para- (2)) + chute "a fall" (see chute).

Some early parachutes had rigid frames. Leonardo da Vinci. And other people. Frameless parachutes followed. Gliding parachutes followed.

=================================
Otto Lilienthal
Study of the German words?
http://www.lilienthal-museum.de/olma/213.htm
"segulflug"

Chanute. Study his major book.
"Progress in Flying Machines," One author wrote about such: "a compilation of aviation information and arguably the most influential book in aviation history. By 1895, Chanute had decided to experiment with hang gliders to find a suitable airframe for a flying machine."

It's late after a long day of work as I'm reading this, and I really did laugh that hard. Thanks Bill!!
 
 
As a point of reference, here's the Mission Statement for the Torrey Hawks Hang Gliding Club (unchanged since 2007):

      "The Torrey Hawks Hang Gliding Club is dedicated to promoting and protecting the sport of Hang Gliding at the Torrey Pines Gliderport."

If some wise guy comes along and tries to redefine "Hang Gliding" to include some new contraption ... then we will feel equally justified in redefining "promoting" and "protecting" with regard to that new contraption. How's that for a solution?

My point is that every word in our mission statement is already subject to common interpretation. Why should the words "hang gliding" or "hang glider" need more specific definition than what we all understand in common usage? Why should we have to get more specific about "hang gliding" than we do about "promoting" or "protecting"?

Try this. Go to Google (google.com) and search for "hang glider" and "paraglider", then click on the "Images" link.

Here's what I got for hang glider:

Here's what I got for paraglider:

I agree with every single picture in both of those categories. If Google can figure this out,*  then I think we're on solid ground using "hang glider". We're making our job way too hard by not simply accepting the meanings of words in common usage.

The US Hawks is a hang gliding association, and I suggest that "hang gliding" is a fine term to use in our mission statement without needing to define it further.
 
 
*Note that if you scroll far enough down on any of Google's images pages you'll find conflicts. But the weight of evidence is untarnished by those outliers.

Agreed, BobK, for the leading statements! KIS principle. Use language that contemporary ears know. The history fun may show in forum articles. We do not want BillC to be taken anytime soon.

Abbreviated Quote by: Frank C.
“My personal opinion would be to not require weight shift as the only control method because that would eliminate almost all ridged wing hang gliders. Most non-flex wing gliders require some sort of movable control surfaces to obtain adequate control, especially in roll and horizontal direction.

If someone told me that my Skysail was not a hang glider, because of the tip "drag rudders", they would elicit some argument on my part.---”

--------------------

Abbreviated Quote by: joeF
“-----FAI struggled with definitions. NASA struggled with definitions. Patentees struggled with definitions. Glider history struggled with definitions. Various levels of sophistication in books have struggled with definitions. When governable parachutes gained in glide ratio there was some struggle with words to describe. Some parts of some definitions from some sources seem stickier than others. Another tactic is to write "For the purposes of our concern in this document or org, we will mean as "hang glider" the following: __________." Just what is said in agreement with readers may be carefully defined or fuzzily defined. The struggle continues. ---”

------------------------

Abbreviated Quote by: KaiMartin
“Seems like you US Hawks founders would like the definition to serve several purposes simultaneously:

1) include all existing devices you want to be included
2) exclude all existing devices you don't want included
3) include all future devices you want to be included
4) exclude all future devices you don't want included

The last purposes are the most difficult. You just don't know what is going to pop up in the future. IMHO, there is no way to know in advance whether or not the future device would make a welcome addition or should be referred to its own orgs. Consequently, I'd not try to deal with future devices at all. After all, the definition can be amended if/when new types of flying devices become viable.--”

I asked Joe if we could separate from our work on the US Hawks Mission Statement the definition of, “What is a Hang Glider?”
Also that we separate this discussion from the BOARD OF DIRECTORS PRIVATE DISCUSSIONS and get input from members outside of the board.
Thanks Joe for going along with my request.
Thanks everyone for opening my eyes to what I thought was a topic that was, cut and dried, short and sweet, plane and simple.
We can revisit, “What is a Hang Glider,” as new developments arise in the future.

There is a consensus that my definition would have been to exclusive and I accept that.
Please feel free to add to this thread your thoughts.
If members of the Trial Board of Directors are in agreement I suggest we return now to the, Board of Directors Private Discussions to move forward with the US Hawks Mission Statement. The conclusions the Trial Board Members come to at this point are not cast in stone but only advisory in nature. Bob K. will move any of the Trial Board Members’ decisions to the, Board of Directors Decisions thread.

I did in fact call my foot launched balloon the "Hangstat" which was using part of the ancient term for human carrying balloons, "aerostat", that name choice did label mine a "hang balloon" as distinct from a hang glider. Not long ago I learned that my name for my particular balloon design "Hangstat" had become a generic term for all "hang balloons". So I guess I've joined "Thermos Bottle" and the others in that exclusive club of unintentional generic name creators. :o You may line up for autographs now. ;)

Frank C.

BTW - Today is my 61st wedding anniversary. Kudos to my long suffering wife. Judy, for putting up with all of my many outdoor recreational activities over these many years. Hmmm......maybe she was just very patient in waiting for me to kill myself???? But then probably not, because she saw the inherent flaw in paraglider safety (turbulence collapse) before I did, and warned me about my intent to fly one. She has reluctantly accepted my recent return to hang gliding at Dockweiler, and my purchase of the WW Alpha, with my promise to not return to mountain flying.

Oh yes, another first for me: The first 80 year old to buy a glider from Wills Wing. Second autograph line is on the right. ;)
