    Somebody on another website asked me about cell phones still ringing or something…

    A cell phone connection (not the most accurate term, but bear with me) does not mean that the cell phone is still active, or in one piece for that matter. You won’t have confirmation of that until the other end answers the phone.

    While the connection is established the phone will make the familiar sound. Only when the network is sure the phone can not be found will the “connection” be terminated. That’s also why you can hear briefly a tone when you try to call someone who has switched off his phone.

    The Dutch minister of foreign affairs has approved the sale of four patrol ships to Tanzania for 30 million euro. The ships will be unarmed, but are delivered prepared to be fitted with machine guns.

    It actually crashed yesterday (or earlier). The image at below site was posted at another forum yesterday at 11:10 in the morning Dutch time.

    Great catch, what is that Ghanian doing all the way in Biggin Hill?

    Not the largest lessor by far, but not a small one either. Their portfolio consists of:

    4 x A319-100, Germania, Syphax
    2 x A320-200, Air Asia
    1 x A330-200, Air Mauritius
    2 x A340-600, Virgin Atlantic
    22 x A380-800, Emirates, Singapore Airlines
    1 x B777-200LR, Emirates
    5 x B777-300ER, Cathay Pacific, Emirates

    So 37 aircraft, of which two thirds is already A380!

    It’s definately a 146 or ARJ. As for which one, your guess is as good as mine.

    On a hunch, I think the reason they build a seperate runway is because the Red Bull air races require a lot of (temporary) support infrastructure. Not just maintenance areas for the planes, but also VIP stands and chalets, media areas, visitor areas and a 100 foot tall fountain spewing Red Bull… ok, maybe not the fountain. All this stuff can not be placed at the LCY platforms. There might be enough space, but it takes several days to build and then dismantle the flying circus. This would tie up the already cramped LCY ramp space and badly impact operations.

    Bit of a lucky shot. Some guy stood right at the fence on a step ladder wearing a light hat. This hat got in frame while the plane passed, making it seem as though the Mirage broke through the clouds. Not surprisingly the other shots where this guy blocked the view, and there where a lot, did not work out. Ladders should be banned from the first row at airshows!

    These two photos where made at a military low-flying area for helicopters. It’s just north of Eindhoven airport (Oirschotse Heide) and is open to the public. You need to be lucky here. Sometimes there are several helicopters at once, sometimes days can pass between visits. Having foreign helicopters is extremely rare, usually only the Netherlands air force and occaisionally the Netherlands police practise here. When visiting here, please keep to the tree line for your own safety, as alongside the helicopters there are also armoured vehicles and other military heavy equipment operating here.

    Let me get this straight. You went from a solar powered plane that folds down to about twice the size of a two-seater Smart car, to a practical interplanetary vessel. And all it took was 16 posts / 2 weeks.

    You might want to start drinking your Vodka per bottle, instead of drinking it per crate. 😉

    with a 98 m span and large lifting body mid section.

    In order to fit at existing airports the plane’s wingspan should be no more then 80 metres, unless you intend to add folding / pivoting wings which will increase the weight and maintenance costs dramatically.

    but only 25 kg / m2 wing loading fully laden

    For that to work you either need giant wings which, again, do not fit in the 80×80 metres box airports are designed for. An alternative is a flying wing, which existing airport infrastructure is ill-equiped to handle as well (gates, airbridges).

    It has 3 hp per passenger power for cruise

    I do not know if that will be enough or not, might be. However, to get the thing of the ground you will need more then that.

    and 1/3 of the frontal area per person compared to small DuckHawk glider.

    Where do you want the 180some people to sit while still maintaining such a small frontal area?

    more efficient solar panels than on the wings

    Solar panels are still too heavy to be practical in aviation. In the future they might be interesting to supplement other power sources, and who knows in the far future perhaps
    they will be light enough for what you have in mind. But that won’t be anytime soon. Also, no solar panels have been approved for use in commercial aviation. Just on experimental kit.

    Last bit, if you want to replace zeppelins, you are running some 60 years behind. Except for some novelty and promotional zeppelins and dirrigibles they have already gone the way of the dodo.

    Nice shot! Did you go by car, and if so where did you park? I am never able to find a good parking spot at that spot.
