Since getting a fitness tracker & scales (fitbit in my case) I lost 18kgs (just shy of 40lbs for our 'merkin friends) in 10 months, and have kept that weight off for more than a year. I do NOT attribute this to the devices, but to a change in diet & activity levels. The tracker & scales did provide targets, and maybe some motivation to keep hitting targets. In my case, 15,000 steps, 10km's & 60 minutes activity a day.
It's not like sitting in the aircraft, and even pilots sitting in the aircraft miss other aircraft now and then..
Miss them all the time! Aircraft are small and the sky REALLY big! I've had warnings from ATC about aircraft on a converging path at the same (reported - probably uncalibrated transponders) altitude, and even though I'm sitting in a low-wing bubble-canopied aircraft (so great vis) did not see a single one! Not a peep on the radio from the other aircraft either - bloody scary!
The reason that the terrorists hide amongst civilians is threefold: 1) they know we're (supposedly) reluctant to target civilians; 2) they want to hide their identity from us, and from everyone else; and 3) they want to intimidate their innocent countrymen (Don't rat us out or we'll kill you and your family).
2 to 3 knots above stall is VERY dangerous. The usual formula is 1.3 x stall speed, so if your stall speed is 40knots, your approach speed should be 52knots. This provides enough leeway for low-level wind shear, and the extra speed contributes to control responsiveness - at stall your controls are FAR less effective than at speed.
Landing at 2 knots over stall speed, if your wheels are 10mm off the runway would indeed make for a light and smooth landing - if you're at 10 meters then your landing will be anything but smooth.
Very true, which is why Human Factors is stressed in flight training now. The fraility of people is what causes failures, in any field of endeavour. Early in my flight training, doing solo cicuits, I was a little high so I pulled the throotle right back - the engine stopped (ever been in a powered-down datacentre - there is nothing so quiet!). I was halfway through thinking 'what the hell do I do now', when my instructors' voice ran through my head (like Obi-Wan), "Fly the aeroplane". I had 1,300 metres of runway in front of me, airspeed and attitude was good, so I just glided the aircraft in - restart and taxi off the runway. It was a great lesson for me.
How does the artificial horizon stay calibrated during cruise? Your real attitude changes as you follow the curvature of the Earth, so you must use the real horizon from time to time to recalibrate the gyros. Same as with a DG.
Quite frankly, I don't know - I only fly behind steam gauges, and only day VFR, however the 'attitude' won't change, but your 'altitude' will. Even with a 'fixed' or uncorrected articfical horizon, you're only going to (logically) climb, as the earth falls away underneath you.
I would imagine that the avionics in an Airbus are pretty damn smart, and would get GPS position fixes and recalibrate the artificial horizon. In the case of flight 447, calibration of the artificial horizon would be of secondary or tertiary corcern - the emergency (the storm and frozen pitot tubes) would have been over quickly (assume a 50 mile storm system at 300 knots means it's 10 minutes before you're out of the storm).
Having said that, I wasn't suddenly thrown into a very high stress situation, with multiple alarms sounding, and the strange aircraft attitudes that are almost certain to occur when you fly into a powerful storm, so as mentioned earlier, it's easy for me to sit here at home to say that!. Aviation has the possibility of getting very exciting very quickly, and I can't help but think that, maybe, there were too many warnings presented to the pilots of flight 447, which distracted them from the task of flying the plane, which after all, is the primary purpose of the pilot.
When I was learning to fly, the instructor would quite regularly cover the flight instruments, and I'd have to fly circuits without knowing how fast I was going, or how high I was. While it is easy to estimate speed & climb from your attitude (nose above the horizon & lots of throttle usually means you're going up, nose above the horizon and no throttle you're slowing down, and will soon stall and descend (quickly too!)), I would hate to have to do that without outside visual references like the pilots of flight 447.
However, I would imagine that a blocked pitot tube would not disable the artificial horizon (and if it does, then why?). The pilots should have been able to keep the aircraft flying using a cruise throttle setting (already set) and the artificial horizon. Having said that, it is easy for me sitting here to say that, without multiple alarms going off in a rapidly deteriorating situation. It could be that flight 447 was a unique set of circumstances, and these guys were test pilots.
Its already been built smaller - actually that was done first as a proof of concept. Have a look at http://solar-flight.com/sunseekerII/index.html - built by Eric Raymond. From the magazine article that I have (Pacific Flyer - June 2009), with an empty weight of 120Kg and a gross weight of 230Kg, this should fit nicely into the US Ultralight regulations, but probably not the Part 103(?) that doesn't require licenses.
A friend of mine lost a limb in a accident with a lathe. When he tried to get a prosthesis, Bluecross/Blueshield denied the request because he wasn't covered. He now beats himself for having wanted to save $30/year on insurance.
But at least he can't beat himself very effectively!
This week is lopsided only if you ignore history.....
It's more a question of land. The Pals want it, the Israelis won't give it, end of story.
As you quite rightly say you shouldn't ignore history, however, you are only considering more recent history and you should look back 60 years. Israel was created in 1948 with land taken away from the Palestinians - all they want is their own land back!
Will their laptop suddenly hibernate in the middle of a presentation because its been idle for more than 30 minutes?
This is probably off-topic, but why the hell can't laptop manufacturers or O/S suppliers make a simple change - if the laptop is plugged into a projector then DON'T pop-up anything over the top of the presentation! It drives me nuts when I see it happen, and it can be embarassing for the presenter (and the audience, depending on what pops-up!).
After pushing my femur through the back of my hip socket I was in traction for 3 months. It is absolute hell staying in bed for that long (aside from the nurses giving bed baths!).
The worst thing was that I wasn't actually sick, I just couldn't get up and walk around - actually I didn't walk around for quite a while, but at least I could hobble!

Australia bends over backwards for US, as they saved us from Japan in WWII, and we're hoping they will save us from China in WWIII.
Actually, I think we bend over forwards for the US

a Malaysia Airlines Boeing 777 en-route to Kuala Lumpur from Perth experienced similar problems.
And the Qantas flight was also going to Perth? I blame all the iron ore thats still in the ground around Perth!

Tarot reading
If you took all the economists in the world and laid them end-to-end, they still wouldn't reach a consensus!
