Story by Neil Larson, the first official "historian" of the 1900's renaissance in hang gliding which was spurred by the leadership of Francis M. Rogallo's insistences in the 1950s impacting the space age solutions and revisits and deepenings of stiffened flexible wings forming the media-set inked "Rogallo Revolution."

New Seedwings 710 took its maiden flight.
This is the 710 152 on its maiden test flight with flaps down and in VG loose. The glider was so close to perfect in every way, only the CG needed to be moved forward a 1/4".
Never before has there been a Sensor this well balance and this light weight. The combination of ultimate performance for a kingposted glider and intermediate level handling for a Sensor is unprecedented. The sizes now available are the 145 and 152.
In-depth airfoil design research has resulted in three rarely achieved goals all at the same time and that is higher lift, higher lift to drag ratio and increased longitudinal stability also with improved rough conditions performance like in rain or with wrinkles and bugs. The new 710 glide ratio is a solid 14 to 1 flying prone.
The construction is typical Sensor 610 F5 frame and full race sail as you would expect. Additional weight savings has been achieved with the addition of a 7075 T6 keel along with the standard and rugged leading edges of 62 mm inboards stepping down to 50 mm outboards. The crosstubes are normal 2.5" 6061 T6.

The weather is really bad over here in Holland. For me this means I need to push the realization of the 2011 Calendar. There are 2 weeks (till Oct. 15th) before the Calendar is designed, so it will be for sale half November via www.svs-design.nl/webshop/
Till now I received some really nice pictures for the new 2011 Calendar, but by
far not enough for producing a new Calendar.
So please, send me ( <mailto:firstname.lastname@example.org> email@example.com )
your Hang glider pictures and if you do so, please include the pilots and
Hang gliders name as well as the location where it is.
You will find at least one of your pictures back on the 2011 Calendar.

Excitement brings eyes open (Photo by historian Neil Larson):
*I also recall the early time, all most innocent, we stepped through time-
We unfurled recycled wings with a painter on 60 Minutes- feet dashed in sand
Grinning you showered with Zest on TV, we didn’t see the bird machine intended-
We had to “Change Our Horizontal into the Vertical” before we flew
As duly noted by an old Venice Wino – strolling on the Metro Depot grass-
We seared albumen into alloy upon a roof top Mid Day “dark room”-
Which dream like seemed as a Stairway to Heaven -
A dusty Parking Garage became Universal Flight Control Headquarters –
In some Hobbit Fantasy Realm of Antique Autos
Each Mistake had a positive result , lifting us higher – closer to Heaven
So we worked hard to think of the most humorously outrageous concepts
Eventually even Dr. Paul outside the box used McDonalds wrappers as fuselage,
Meat Market Shrink Wrap became wing surface &
Skateboard wheels made landing gear & put the tail back in front like Wilbur
For a moment leading Edge Scientists threw away Slide Rules
& began to take their Ques from Hang Gliding Boys in T-shirts & cutoffs
Then we lived Hanging Loose & Low & Slow…Inspiring the all World beneath us
Sharing all our dreams & ideas with one another , Smiling as we Gave- Everything Away
First names were all we knew, phone numbers scribbled on pages,
A sport spawned from Word of Mouth , the Underground Network began-
“Faust-Speak” twisted inside out, stretched like a rubber band on a Balsa model airplane-
You have been the elastic motor to energize the propeller of our dreams
We thank You Joe , for having the Spirit of the Renaissance Men who leapt before you-
Breathing Inspiration Life into the lives of Generations around you.
I pause to humble myself knowing my life is richer and more full
For having known you as a friend….

From Mike Meier:
Dear USHPA Director,
As you prepare for your semi-annual meeting, there are a couple of issues that I would like to ask that you consider.
As you may be aware, the USHPA now has in place a process for the sanctioning of hang gliding aerobatic competitions, and a rule book for conducting such competitions. The justification for incorporating aerobatic competition into the USHPA competition program was stated in the following announcement on the http://USHPA.aero web site:
Aerobatic competitions have been held in Europe for some time now. These are exciting for both participants and spectators. There are many talented, world class actually, aerobatic pilots here in the USA. Unfortunately, there are few opportunities for these elite athletes to compete in their own country. This is also a missed opportunity to promote our sport before larger groups of spectators. The recommendations from the Symposium will include an organizational structure for aerobatic competitions, including ideas for scoring, suggestions for training scorekeepers, resources and incentives for event organizers, criteria for fairly selecting our World Team, and a move forward plan.
Given that I have spent a substantial part of my career in hang gliding involved in issues that relate to pilot safety, I feel compelled to offer some comment on the USHPA's decision to promote aerobatic competition in hang gliders. I have expressed these concerns previously to the USHPA president, to my regional director, and to the chairmen of the safety and training committee, and would like to address these concerns to the entire board at this time.
No hang glider has been designed, tested, or certified for aerobatic flight. This is true in spite of the fact that The HGMA Airworthiness Standards (the oldest airworthiness standards in the hang gliding industry) have contained, from the beginning, a specific, and fairly straight forward provision for certifying gliders for aerobatics. (HGMA standards available at www.hgma.net). In the 32 year history of the HGMA, 345 different hang glider models have been certified by 37 different member manufacturers. Not a single glider has ever been certified for a single aerobatic maneuver.
A fundamental design aspect of the vast majority of hang gliders - the fact that the pilot hangs suspended beneath the wing from a flexible tether, and depends for his ability to control the wing on that tether being positively loaded - makes hang gliders inherently unsuitable for aerobatic flight. Airplanes which are used for aerobatic flight are designed to be able to be flown inverted and under negative load, with the pilot retaining reliable control of the aircraft. Hang gliders cannot be reliably controlled while unloaded or loaded negatively. Hang gliders also have unreliable structural margins under negative loads, and are not designed or tested to be structurally reliable even under positive loads during maneuvering flight at speeds in excess of approximately 50 mph, while the most common aerobatic maneuvers routinely involve maneuvering at speeds in excess of 65 mph. Aerobatic flight in hang gliders is a purely experimental form of flight, which takes place far outside the flight envelope for which the aircraft was designed and tested. Numerous incidents involving structural failure have occurred in hang gliders in aerobatic flight, and numerous incidents of dangerous loss of control by the pilot have occurred as well, and these incidents have involved some of the world's best and most experienced aerobatic pilots. It is one thing for pilots as individuals to choose to pursue extreme forms of hang gliding outside of the limits within which it can reasonably be expected that such flight can be conducted with reasonable safety. I have no objection to pilots who choose to make that choice, (providing that it is an informed choice - based on numerous discussions I have had with such pilots, it is my firm belief that most times it is not an adequately informed choice).
When it comes to the national association promoting this type of flying, (and by extension fostering the idea that this type of flying can be considered essentially safe, normal and acceptable as opposed to inherently unsafe, extreme, and completely experimental), I have a decidedly different opinion. I think it is inconsistent with the most basic concepts of safety, and therefore irresponsible in the extreme for the USHPA to promote aerobatic flight or aerobatic competition in hang gliders.
For a more detailed explanation of the design limitations of hang gliders and how those limitations relate to aerobatic flight, and why aerobatic flight is fundamentally different from other forms of flight in hang gliders, I invite you to read the following technical article on the subject:
http://www.willswing.com/Articles/Artic ... aerobatics
The above article, while fairly detailed in scope and content, is also written to be as accessible as possible, and it dispels a number of inaccurate ideas that I have repeatedly heard expressed regarding the technical aspects of hang glider airworthiness and aerobatics. I also invite any of you who have questions on the technical aspects of this issue to contact me at any time, by email or by phone.
I understand that those pilots in the United States who wish to compete internationally in aerobatic competition may need to have a process by which a team can be validated by the USHPA in its capacity as the representative to the CIVL for those pilots. However, I think that there must be ways in which that can be done without the USHPA being directly involved in the promotion and sanction of aerobatic competitions. My recommendation would be something along the lines of the aerobatic pilots forming an organization of their own, administering their own competition rules and pilot ranking system, and having the USHPA simply agree to recognize that ranking for the purpose of team selection to CIVL events. Again, my concern is not with the existence of aerobatic flight or aerobatic competition, but with its promotion by the USHPA, and with the inevitable result from such promotion that the message is being conveyed by the national association that this is an appropriate and accepted form of flight in hang gliders.
The second, and related issue that I would like the board to consider has to do with technical matters in general, and how those might inform actions that the board or its representatives may decide to take. The USHPA Mission Statement says that the USHPA will (among other things):
Maintain a working relationship with manufacturers and the manufacturers’ associations that will serve to promote the sport. And Represent the membership at the national and international level through the NAA, CIVL and FAI
In the course of representing the USHPA, and US pilots and their interests to the CIVL, it will often be necessary for the USHPA representative to bring to bear on that process a significant understanding of technical matters. The most reliable source for such technical understanding would be the manufacturers and the manufacturers' associations - i.e. the HGMA. However there has been very little outreach from the USHPA to the HGMA or the manufacturers for technical support, and I have observed that a number of CIVL actions, which have been supported to varying degrees by the USHPA CIVL representative, have been inconsistent with a proper technical understanding of the issues involved, and have as a result been counterproductive to the desired ends, and to the interests of the pilots. I would suggest that this process could be improved by a closer cooperation between the USHPA and the technical community of the sport of hang gliding, and I would urge the USHPA to be more proactive in availing itself of the technical knowledge and experience that exists in that community.
I thank you for your consideration, and I wish you a productive and successful meeting.
