  1. Haha what you been drinking today Doug? Come now don't spoil the story.... can't you add a yarn?
  2. "After 15 years of development, an Israeli tech firm is optimistic it will finally get its 1,500 kg (1.5 tonne) [/url]passenger carrying drone off the ground and into the market by 2020..." I wish them well and like the reduced potential for blade strike but it doesn't come across as very stable or efficient looking to me. And 1500kg?
  3. If I can comment on that Frank inverse square reduction from a point source is 6dB per doubling of distance and 3dB from a line source in ideal free-field conditions. This is the SPL propagation loss, in terms of perceived loudness approx 10dB represents a halving so yes it's a considerable reduction in loudness but not four times... One could have a degree of respect for the Greens if they actually never used things like petrol, coal-fired electricity or flew in aircraft. Or made noise.
  4. Well that's not nice; the usual procedure is the reverse.
  5. Nonsense, every last one of the 'poor minnows' are well overpaid and no longer have any concept that they are supposed to be employed as our servants. I guess making the rules, enforcing the rules and getting pay higher wages and with better conditions will do that... the whole show needs a role reversal. Start by locking their wages at private sector average less 10% and then lock CASA staff numbers to aviation industry employment numbers. No reason it should not remain proportional or be decreasing as technology continually improves their productivity. That's how the real world works.
  6. During a recent flight by Tier 1 Engineering in Costa Mesa, California, [/url]a full-size fully electric helicopter flew successfully through hover, takeoff, cruise, and landing. The battery-powered helicopter reached an altitude of 400 feet above the ground and a maximum speed of 92 mph during the short but historic five-minute flight. Nice, but was hoping it might be quieter, seems copters are all prop noise. Also 500kg of batteries is a drag... instead a really long extension cord?
  7. Welcome NK, most important to talk to some past or current students. Also ask the school about their average hours to licence (or certificate). Some will try to milk you for as long as they can. After that quality / condition / type of aircraft and facilities etc... and do you click with the instuctor(s).
  8. Welcome Geirt, and such a beautiful country!
  9. This is a bit of a head-spin:
  10. As you do... [/url] THE FBI is investigating claims a Jordanian student pilot deliberately crashed a small plane near the headquarters of a military jet-engine maker in Connecticut, killing himself and injuring three others. ....the 28-year-old pilot, Feras M. Freitekh, told his instructor, Arian Prevalla, he didn’t want to fly the plane any longer.
  11. I hope Bex will buy the operation and get it chugging along again to make the Bexmotor. Sad time for Ian, his family, employees and of course any creditors. I think this engine had all the hallmarks of being the best currently out there. Ian is indisputably very knowledgeable in this field, it's a serious loss to the whole industry. Meanwhile not a single person at CASA has lost even a dollar of their generous pay.
  12. I don't get the point? You can attach the cage to a conventional six axis arm, it's much more compact and faster responses than what is seen here. The only benefit I can see of the cable system is if you wish to move more around the space i.e. further distances of travel.
  13. Pausing for maintenance due to the hours clocked up in three days? Also the flight testing should tell them they need to design better seats. The base is not so comfortable.
  14. Whoever designed the undercarriage had a sense of humour... (that's humor to some)
  15. For type 2 I said, accelerates the problem. Tends to make you plenty fat also (or even fatter) = more problems.
  16. Some doctors (appallingly IMO) prescribe insulin injections for type 2 diabetics so I take it 'insulin-controlled' could mean either type.
  17. " [/url]NASA is developing a stiletto-like plane wing that's so long and thin that it needs a truss to hold it up. The longer, thinner, and lighter truss-braced wing, as it is called, is aimed at making future commercial transport aircraft more efficient and less polluting." A broader flat-bottomed lifting fuselage might help too... well let's hope it uses a lot less fuel because it has a lot less available storage space for said fuel. Hey who'da thought, they've sort of reinvented the Jabiru.
  18. Listening to head-banging music? Busy playing Pokemon Go?
  19. "The U.S. Army Air Forces had captured the flying wing prototype—along with hundreds of other German aircraft—near the end of World War II. In April 1945, George Patton’s Third Army found four steel-and-wood Horten prototypes; of three airframes, the V3 was nearest to completion, and was shipped to the United States."
  20. You are right, it was badly worded. Poor circulation does not in itself create the pain; according to the experts over time it can lead to degeneration which in turn gives the pain. Most can be ameliorated by exercise This is good advice. Too often one hears the opposite (don't bend, lift nothing etc)
  21. Yes. Back pain is also frequently associated with poor circulation... can be a sign of atherosclerosis. Both are related to poor (eg western) diet and lack of exercise.
