  1. Re:Always a loser... on Farewell To The Concorde · · Score: 1

    I wonder if you have EVER actually flown in it ? If you have, you must the coldest, most boring individual I have ever met ?

    Its only noisy on take-off, once in cruise its quiet (certainly no noiser than a normal airliner), and the rock-solid feeling of smooth stability is unlike anything I have ever experienced.

    Yes, its not the biggest airplane inside, but then, you're not on it for 12 hours are you ? Its comfortable enough, and they ply you with booze and food all the trip.

    When I flew, we left an hour after the normal scheduled flight to London, overtook it at 60,000 feet somewhere over Egypt, and landed in London an hour BEFORE the scheduled flights - one hour supersonic took over 2 and a half hours off the normal flight time.

    As for safety, Concorde airframes were very low time, and the planes (certainly by British Airways) were very well looked after. It had problems with rudder sections and compressor surges, but if development was continued after the first block of aircraft was built, these problems would eventually be solved. The crash in France was caused by a part falling off another aircraft and insufficient runway checks at the Airport - many air accidents are caused by a chain of unconnected events - it has bad luck the tyres blew, bad luck the wing tank ruptured, bad luck it ignited. I would still feel safer in a Concorde than a 747.

    Being British and an Engineer by profession, I can say its the one thing that you see and feel a national pride - we don't have much to feel proud of these days and it was a quantum leap forward in technology, and I feel we are all poorer that it was never taken forward - there is no reason why supersonic airline travel couldn't have become a normal occurrence if development was continued - I read today that plans and drawings were started for a successor.

    I'll look up to see the last departure for NY this week as it flies over London at 5:30 and think sad thoughts.

    If you HAD bothered to read the Nasa Web site, you would have found that they DID credit him:

    Jon Burnett, a teenager from South Wales, UK, was photographing some friends skateboarding last week when the sky did something very strange. By diverting his camera, he was able to document this rare sky event and capture one of the more spectacular sky images yet recorded. Roughly one minute later, he took another picture of the dispersing trial. What is it? Experts disagree. The first guess was a sofa-sized rock that exploded as a daytime fireball, but perhaps a better hypothesis is an unusual airplane contrail reflecting the setting Sun. Bright fireballs occur over someplace on Earth nearly every day. A separate bolide, likely even more dramatic, struck India only a few days ago.

    The lad's own picture and his fireball picture have been published in a number of newspapers with quotes from Nasa.

    Also, he sent the picture to NASA - they didn't steal it.

    This is a PDF file of a study done by the CAA in the UK (equivalent to the FAA) on cellphone interference against instruments. It was done in a laboratory to model in-flight circumstances.

    To quote from the report (6.1) :
    The tests revealed various adverse effects on the equipment performance from simulated cellphone interference. Although the equipment demonstrated a satisfactory margin above the original certification criteria for interference susceptibility, that margin was not sufficient to protect against potential cellphone interference under worst case conditions.

    So until there is concrete evidence one way or the other, erring on the side of caution may be advisable - its also one of the last places where you don't have to listen to some dickhead chatting on the phone in a loud voice.

  13. Legal info from the website on Low-power FM Transmitters Banned in UK · · Score: 2, Informative
    Extracts from the Website

    Section 1 of the WT Act 1949 forbids the installation or use of wireless telegraphy equipment (radio) in the UK mainland including Northern Ireland and territorial waters, the Isle of Man and the Channel Islands, unless:

    • an appropriate licence has been obtained from the Secretary of State,
    • there are in force Regulations exempting it from licensing.
    Short range radio devices

    More and more convenience devices now utilise radio in their operation. Car alarms, wireless door chimes and garage door openers are common examples. Unfortunately not all of these are manufactured in accordance with the relevant technical requirements. The use of non-compliant equipment, is an offence and can lead to interference to authorised users of radio.

    It is an offence contrary to the RTTE Regulations to place on the market non-compliant apparatus.

    The whole point is spectrum is regulated in the UK and unless the equipment is licensed, then its illegal to use it.

    If this thing worked at an exempt frequency, it would be ok, but because it uses the FM Broadcast bands, its not approved for use.

    I would also presume the importer wont sell them simply because they could be prosecuted and would have zero defence.

    The Piccolo is indoors only or else on a day with zero breeze.

    The main posters comments are spot on - I used to fly .30 rc helis for a while and they are very hard to fly - even with gyroscope stabilisation and computerised transmitters.

    The best advice is don't buy one unless you are serious about learning to fly one - its expensive and you will bend it on numerous occasions, although everything is repairable.

    Also, safety first - even a little .30 copter has a lot of inertia in its rotor blades at full power and could cause some serious damage to someone.

    Having said all this, when you eventually manage to get it into a stable hover for as long as you want, its a real feeling of accomplishment.

    I'll second this. These little copters are unusable in anything but zero wind or inside.

    If you want something you can use outside, you are talking about a 5-6 foot rotor span and .35 cu in engine with a rotor speed approaching roughly around 1000 rpm at full whack. If that hits anything it's going to cause a lot of damage/injury/cost - and thats a baby trainer `copter.

    They are VERY difficult to learn to hover, you need literally training wheels until you can take-off, hover, move around and land, even in wind, otherwise you'll be replacing tail booms, rotors, drive shafts etc. etc. all the time. Even with a gyro-stabilised tail rotor (i.e. adjusts to correct heli yaw movement) they are still fiendishly difficult. When I used to fly there was an endless procession of kiddies who would appear for a couple of weeks at the site with their brand new helis, only to seem them get smashed up all of the time.

    I flew in 1993 from Jeddah to London - I had a standard BA ticket, but due to special offer for 400 pounds more I could fly 1-way on Concorde - needless to say I took it ! (I met someone of the plane who I knew - the regular BA flight had been overbooked and the first four people in the queue without seats got transferred from economy on a 767 to Concorde for nothing !)

    Takeoff was incredible - I was seated at the back and the noise was phenomenal, as was the feeling of being pushed back into your seat. Concorde takes off at a much faster speed than a normal plane and it shows.

    When we went supersonic, the pilot informed us that he would lite the outboard afterburners first, followed by the inboard, just to get us through the sound barrier and supersonic. You then felt a small push in the back, followed by a much stronger one, and the mach indicator clicked over Mach 1.0. (Apparently the afterburners are only for takeoff and supersonic accelerating - the Olympus engine cruises at Mach 2.2 without afterburner, it user special ramps on the air intakes to slow the air down to subsonic speeds for the engines).

    In cruise, looking out the windows was almost black above, with a definite curvature of the earth. It was also like walking on the ground - no sensation of movement. I went up to the cockpit and was amazed to see valves glowing behind panels - all mechanical instruments with a flight engineer. There was also a gap behind the cockpit between two panels that was about a foot wide - apparently on the ground you'd be hard pushed to put your fingers between in, such is the expansion of the fueslage.

    Its a fantastic feeling, flying at such speed and you have to marvel at the expertise of the people who designed and built it. At Yeovilton in Somerset you can wander around a test Concorde, walk underneath the wings - the complexity is astounding.

    Lets hope a way is found to keep one flying (I think Virgin Atlantic were after one), I don't really blame BA and Air France for retiring them, if they are not making any money now and the cachet of them has gone somewhat.

    What memories - to anyone who can get a flight in before its grounded, spend the money and do it - it may be many years before you can do something so special.

    This whole argument about mobile phone infrastructure is just the various comms companies salivating at the nice fat US, UK, UN or whatever funded contracts. (Which, make no mistake, will ultimately still be funded via oil sales)

    As for the CDMA/GSM arguments, people (when they can afford them) will make the simple determintation - what is cheap. Also, if everyone else for a 1000 miles in every direction of iraq uses GSM, CDMA is a non-starter. Unless I'm wrong, EVERY country in the area that has installed a mobile network has gone for GSM.
