Designer also offers to check on the fonts used as well as the urckgaobnd colors. Some fonts may not bring out a professional look and also at times aren’t readable. Some fonts aren’t available on the computers of visitors which may crease some problems. It’s safer to make use of the usual but professional looking fonts. Designers may also limit the pictures that they include to keep the site fresh and clean. They might also minimize graphics in their design. Most of the time, the white space presents a better overall appeal.

I am sorry but you are totally wrong. The weight is all part of the equation and the weight of a concrete glider is so much more than a light weight one it can’t glide anywhere near as far.

The concrete canoe website in the link still looks like the most poorly designed website this side of 1995, almost 5 years later.

Re: Concrete Glider
The Germans built a few hundred gliders which had steel-skin airfoils filled with concrete. The craft, dubbed Hagelkorn (Hailstone), looked somewhat like a modern high-performance glider. Its glide ratio was relatively high, and the high weight of the airframe and explosives meant it would glide at high speed (a few hundred mph).
It was to be carried to altitude and released from the relative safety of the east side of the English Channel. A few were used, with some success.
One example is in the Smithsonian’s National Air and Space Museum collection.

Airspeed, airspeed, airspeed – the three things that these aircraft needed most. (Same with bamboo aeroplane.)

They should have made something with longer thinner wings(something that acually resembles a modern glider)that could be dragged behind a car and instead of supporting the concrete internally they should have wrapped it externally with carbon fiber. That way they could have made fairly large ultra thin wing and even could have made it in sections using the carbon fiber.

As a young child (10-12) I stood very close to the tracks and hung on to the pole of the crossing arms. I felt the pull of the train and had to hold on for all I was worth. Never tried that again! I don’t believe they proved it a myth!

OK. Mythbusters needs to do a follow up on this one. I know 10 & 12 year olds that weigh less than the test dummy “TED”. They use this busted mythbusters episode as an excuse to stand too close to the tracks. Every time I hear about a train vs. pedestrian in our area I fear it will be one of these kids. Adam & Jamie…Please do another episode with less weight…or at least go back and qualify what you’ve done.

I don’t know how Adam and Jamie could reproduce the exact set of circumstances, but an acquaintance of mine and his colleague were sucked into a passing high-speed train whilst bird watching in a railway cutting somewhere, I believe, in eastern Europe. My acquaintance was severely injured and spent many months in hospital. His colleague was killed.
