Since 1972 Eric has been a glider pilot in Frederikssund-Frederiksværk Flyveklub (FFF), a club organized under Dansk Svæveflyver Union (see The Danish Soaring Web Site). I prefer flying real gliders such as our club's DG-300 or as a Certified Instructor teaching people to fly in the club's Twin Astir which is a two-seater glider. However, when weather or time does not allow for real flying, I do cheat and fly a powered glider (yes, such things do exist, just as there are sailboat with engines). See a picture of the nice powered glider that I own a share of (photographed by Jan Winterskov). It is a Dimona HK 36 TTC 115 built by Diamond Aircraft in Austria. It appears with me in the picture above which was taken by my wife on August 5th, 2005 at the Rostock Airport where we stopped for lunch on a weekend trip to Berlin. Although it can be used as a fair glider, it is mainly used by glider pilots as an inexpensive powered aircraft. It cruises at up to 110 knots, climbs at up to 11 knots. It climbs so well that it has a tow hook, so that we can tow other gliders. I have flown it as far away as Paris, Dresden, and Oslo and use it regularily to fly to meetings in Aarhus and Aalborg and on visits to otherwise fairly inaccessible small Danish Islands (e.g., Læsø, Anholt, Ærø, Fur, Endelave, Samsø, Vejrø, Sejerø, Tunø, Als, Fanø, and Femø) where the Super Dimona's great short takeoff and landing characteristics (needs only a 1,000 foot runway) make access to even the smallest airfield possible. I have also used it as a cross country power plane on trips as far away as Gotland in Sweden, Berlin, Brussels, Oslo, Dresden, Koblenz, and Paris, France. Diamond's division in London, Ontario, Canada has pictures and technical info where the aircraft is called the Katana Xtreme DA20 HK36TTC. If you are interested, you can also see more information about the group that owns the plane.
For urgent business, send an SMS message to my cell phone: +45 40 25 16 50 (best) - or call it and leave a voice mail message (OK, but response is variable).
When is the new millenium?? That is, according to the calendar?
If you ask the US Naval Observatory (if you believe the Americans) or the Royal Observatory Greenwich (if you are more inclined to believe the British), the answer is January 1st, 2001. Why? (Note: the links to the two observatories are now obsolete, so I have replaced them with links to archived versions of the pages at www.archive.org). Or ask the Canadians (archived).
I find the following quote from the observatory in Greenwich quite interesting:
We have received a great deal of e-mail regarding the start of the 21st Century. It is interesting to note that this is not the first time that this controversy has arisen. The Times must have received many letters towards the end of 1799, since its editors felt moved to make the following comments about the beginning of the 19th Century:
"We have uniformly rejected all letters and declined all discussion upon the question of when the present century ends, as it is one of the most absurd that can engage the public attention, and we are astonished to find it has been the subject of so much dispute, since it appears plain. The present century will not terminate till January 1, 1801, unless it can be made out that 99 are 100... It is a silly, childish discussion, and only exposes the want of brains of those who maintain a contrary opinion to that we have stated"
The Times, 26 December 1799
Despite this, the majority of the world appears unable to count and so believes in calendar-wise incorrect turn-of-the millenium and century dates. (If enough people believe in something that is factually wrong, it becomes an accepted "fact", sigh.)
