Consider:
Types, sorts, models, sub-models, mod of models, flavors, categories,..., but all are Otto Wings (hang gliders).

Nomenclature?  Have fun:

• Otto Wing.       "Sacrifices must be made."  Otto Lilienthal's last words.
  
      Look at any hang glider and see if you might call it an Otto Wing, not that Otto Lilienthal did or did not precisely design the wing, but because Otto Lilienthal might have had the most influence on hang gliding than others.  Category thing! Self-soar or "auto-soar" or "otto-soar"... with Otto Wings.
   
• Types by immediate makers or making company?  
  See, an Otto Wing of type Burns! An Otto Wing of type Pilcher!
  An Otto Wing of type Pelzner! An Otto Wing of type Dahl! 
  
  (Otto sounds like "auto" or meaning self; self-wings, hang gliders; self-soar wings by Otto followers, by those evolving from spirit and example of Otto Lilienthal ... ).
   
•  Now we have several hundreds of hang glider designs and scores of branched types ...but they are types of Otto Wings. 
     
  Type: Cronk.    Type: Miller.  Type: Prentice.  Type: Dietch   Type: Kiceniuk.    Type: Colver.  Type: Barish. Type: Jalbert.  Type: Haggard.   Type: Boone.  Type: Koman.   Type: Paul.  Type: Richards.   Type: Wanner.  Type: Beeson.   Type: Breslau-1908.    Type: Palmer.  Type: Chanute. Type: Spratt.   Type: Bensen.  Type: Paresev.   Type: Rogallo.    Type: Richards.
  Type: Jensen-1941.  Type: Jensen-1972.    Type: Lovejoy.  
  Type: Lovejoy High-Tailer.  
  Type: High-Hat.  Type: Horten.  
  Type: ___??__.      Note:  hundreds of other types of Otto Wings are not listed here yet.
  Send in your found type or sort or category of Otto Wing:  editor@upperwindpower.com
     
• I fly Otto Wings, not a powered aircraft, not a spacecraft, not a parachute, not a missile, ...    Many types.  Armstrong flew nearly 100 types of Otto Wings; he is still flying some types of Otto Wings.
   
• There was a type of Otto Wing in a gliding club in Breslau that was a hang glider that precisely used a cable-stayed triangle control frame with pilot hung behind the TCF ....and such was not the first use of such mechanics, the invention of which goes even earlier than 1887 a good distance back.    There are many types of modern hang gliders yet to be designed, built, tested, and flown; they might still be called Otto Wings of type ____?_______.    
   
• Near to this topic is "Sorts"  which see discussion thread at OR: HERE.   Otto Wings come in types and sorts and flavors and colors and pilot-hold variations and models of a family.     Fun!       Otto Wings are hang gliders; hang gliders are Otto Wings; try it out~~~                 JpF    
  Add to this nomenclature exploration:      editor@upperwindpower.com   Otto Wings of sort that use the TCF (early instance, not earliest: Breslau 1908).    Otto Wings of sort that hand hand-grip combined with arm-pit on parallel bars.   Otto Wings that had or have aerodynamic controls controlled by pilot torso motion.   Etc. Control distinctions. Single plane, double lob, multiple planes, SS, DS, inflated, collapsible, solid, etc.    Parade of Otto Wings!
  How does it sound:
  My Otto Wing is Model ___ made by ____,
  a neat hang glider!

• Nice added note, Dayhead!                  PM 17Nov2010 at OR
  
  Top list added:
  * Pelzner Gleiter and replicas (see post below)
  * Wright gliders (think of the lower wing and pilot as the tensionally hung aspect under the high hat upper parasol wing....to get the "hang" permit here)
  *Sensor series of Otto wings    [Dayhead happy wing, see his note below at OR]
  *
  Eddie Paul in 1970s build an Otto Lilienthal for movie set use.

  Of Otto Lilienthal's 17 or so gliders, I had not seen the image I just posted in

  Your note that today with careful work we probably could get a neat-flying near-replica going is right on!.
