TheSoaringSiteUpdate on 60 AcresIn the March issue of RCSD, wediscussed the threat to a flying sitecalled 60 Acres. Since then, we receiveda heads up from Bill & Bunny,directing us to the web site of TheSeattle Times. The headline on the webpage said, “Sewage plant put on holdfor a year,” by Nick Perry, Seattle TimesEastside bureau. Two paragraphs in thearticle caught our eye:“As well as feeling pressure from cityofficials, county politicians and staffhave been the target of a well-organizedcampaign by the Seattle AreaSoaring Society, which has flownremote-controlled gliders in the southsection of 60 Acres for 30 years. Thesociety has sent out thousands ofletters and e-mails urging that its partof the park remain untouched.”“We are very happy with where it’sheaded,” said Sherman Knight, asociety member and Kirkland lawyer.“But until the county starts breakingground somewhere else, we are still alittle nervous.”Hmmm... We always knew that the SeattleArea Soaring Society was a “well-organized”group! Our best to all of you as thestory continues to unfold!New Aeromodelling WorldRecord Attempts - 03.06.2003And, in another heads up from Bill &Bunny, they forwarded an e-mail messageregarding new aeromodelling world recordattempts. What follows are the details ofthe message.“This is a message from the FAI‘Aeromodelling Information’ mailinglist.” (CIAM Home Page: http://www.fai.org/aeromodelling)“FAI has received the following ClassF (Aeromodels) record claim:Claim number 7793:Sub-class F3B (Glider)May 2003F3: Radio controlled flight CategoryType of record: N°158: Distance to goaland returnCourse/location: El Mirage Lake, CA(USA)Performance: 1.90 kmPilot: David L.
