Pictures From ASI
From : Kjell Folkesson Hi Atul Dev, I really hope you are fine. I write to you because I´m responsible for PR for the Swedish Airsport and I have some problems and one major problem is that about pictures. I have very few good pictures which I can use for free and which our newspapers, etc can use for free. I and Bengt-Eric Fonsell (our President) talked about it and he told me to ask you if we are allowed to use pictures from your library on the net and other pictures from Airsport Magazine (by the way, great magazine) ? Best regards,Kjell Folkesson Editor's Response: You are most welcome to use any pictures carried in Air Sports International as long as you acknowledge their source.

Article Entitled "The Physical Description of Lift"
From : Mark Sivazlian Dear Editor, I enjoyed very much reading the article entitled "The Physical Description of Lift" by Anderson/Eberhardt on your web page. I assume this article was taken from an issue of your magazine. I spent 9 years as a Naval Flight Officer, spending most of my time in the A-6 Intruder and LC-130 "Polar" Hercules. I have left the Navy to pursue a business as a paragliding instructor. I am additionally educated as an engineer (albeit Nuclear), and have long been aware of the lacking elements of the popular explanation of lift. Although many of the principles outlined by Anderson/Eberhardt might discourage the basic paragliding student, I feel that could use the material in the article as a guide to introducing a "proper" (but still incomplete) explanation to how their wings work. If it is possible, please e-mail me information of how I might obtain a copy of that article or the magazine it was published in. Many thanks for your time. Best wishes,Mark Sivazlian

Information About The Viper Microlight
From : André Jacobs Dear Editor, Thanks for posting airsports on the net - your mag is truly great! Can you please help with information about the Viper microlight, which I understand is made in Germany and in Italy. The under carriage is made in Germany by Eurofly and the wing, known as the 'Hazard' in Italy. I can't find any information about these companies on the net - do you know where I can get them or phone/fax numbers ? Thanking you,André Jacobs

Human Powered Aircrafts
From : Gard Erik Skoglund Dear Sir, I am a student at Coventry University, 2nd year MDes Transport Design, currently participating in a group research project on Human Powered Aircrafts. I've taken the liberty of sending this letter to the mailing list, asking any of you to read it, and hopefully contribute with some thoughts and ideas. Any reply (privately to my e-mail account is preferred) with any information would be very helpful. Our aims are to find out who the people making and flying these aircrafts are, if this interest is in any way linked to other "extreme" interests or possibly interests in engineeering. We need to find out why some people are concerning themselves with HPAs, the social context around them. An other very important issue in the report will be cost. It is the intention of the brief for the group to come up with a design proposal, with the marketing to go with it. We will have to show how the crafts are to be manufactured, how many a year, what kind of material is used, etc. The Internet has been used extensively in the quest of finding out as much information as we can. However, we have not been able to conclude as to how much it actually costs building an HPA, neither are we aware of the time needed to make one. Today, the role of the HPA seems to be mainly in racing, trying to set new world records. One of the conclusions of the report will be whether there is a potential market outside these races. If there were a fully finished, perfect-working HPA, would it be interesting to people who already were doing things like parachuting, paragliding, so-called extreme sports (in air)? Could a whole new market be discovered? Safety and legislations are also of importance. Information about these topics would be extremely helpful. Finally, we would like to ask you if you'll allow us to send you a questionnaire, asking more specific questions, after all research so far, has been analysed. Any further information other than the queries stated here would be greatly appreciated as this is a rather special case, quite difficult to research. Gard Erik Skoglund

Anti-Collision Colour Markings
From : Herbert Pirker Dear friends, To avoid mid-air collisions and to make anti-collision colour markings or strobe lights mandatory for gliders flying in competitions: As the nominated chairman of the IGC-subcommittee for anti-collision colour markings I need as much infos as possible about the effect of colours on gliders and on other flying objects. Who can help? Rumours tell that an investigation of the German LBA some time ago has shown white - because of its high reflectivity - to be the best anti-collision colour !! I think this to be ridiculous, because not the reflectivity, but the visibility (for instance against any light or white background like clouds, snow etc.) seems to be of importance. Nevertheless, who knows more? Also, who has got some experience with strobe lights for gliders ? Please send hints, links and infos to my email: bugwiper@ping.at Thank you.Best regards Herbert Pirker
