    The reality is, this is just a cost issue. With oil prices at $25 a barrel, the only viable commercial source is to pump it out of the ground in the middle east. With oil prices now at the $40 a barrel area, lots of other sources become viable. The tar sands in Alberta contain more oil than the entire underground reserves in the middle east, but it's more expensive to extract. With world prices in the $40 area for a barrel, the tar sands become a profitable venture extracting the oil.

    There is no shortage of oil in this world, there is a shortage of cheap oil. That shortage is mostly artificial, oil companies have not been investing in infrastructure in the middle east for the last 15 years, and what's there is old and wearing out. That investment is not going to happen as long as there is the current level of political instability in the region. It's now been demonstrated, that invading and installing a puppet government actually decreases the stability of the region, and invites all kinds of attacks on foreign sponsored oil production infrastructure. In simple terms, the well has been poisoned.

    There's lots of 'extractable' oil in this world, it just cant/wont be extracted for 25 dollars a barrel. Personally, I'd rather see us burning cheap middle east oil in the short term, and leave our own reserves in the ground for the grandchildren to enjoy, they can sell it to the usa for $100+ a barrel after the middle east has been sucked dry.

    In case anyone's interested, skydiving is a cheaper way of obtaining a similar experience.

    There is NO comparison between skydiving and true freefall experienced in parabolic flight. While skydiving, you get this 'minor' force of air resistance, and if you think it's really minor, explain why it's such a big deal when 140 mph winds hit shore in a hurricane, those are the winds you experience while skydiving. In parabolic arcs, you are sheltered from the air resistance within the confines of the aircraft cabin, the local air mass is traversing the same trajectory, so it's not providing you with air resistance.

    I've done both, and the closest you are going to get to true freefall without use of an aircraft, is scuba diving. Get your bouyancy properly neutral, get rid of your fins, and hover out in the open, well below the surface, and well clear of the bottom. It's still not nearly as cool as the freefall in an aircraft cabin, but it's a damn site closer than a freefall skydive.

    The primary difference with skydiving is the lack of walls.

    The primary difference skydiving is the 100+ mph wind, which provides lots of air resistance, against which you can work to do all sorts of maneuvering. Maneuvering is determined by newtonian physics, f=ma, and the wind resistance in a skydive provides plenty of f to work with. To really experience 'weightlessness' you need to get into an environment where there is no inital vector for the f element of the equation. In the aircraft cabin, the walls shelter you from that wind resistance, the aircraft itself is being flown on a trajectory to neutralize all the other forces.

    Keep one more thing in mind, there is NO free lunch. If you go for 25 seconds at zero g during the pushover, expect 25 seconds of two g during the pullup. Newtonian physics do adhere to the TANSTAAFL principles.

    The type of rocket motor used on SS1 pretty much precludes it blowing up from a fuel induced explosion. The fact that it's an aerodynamic structure, with wings etc, gives it a much higher probability of coming apart in flight due to stresses on the airframe. SS1 is not Rutan's first attempt at a supersonic airframe, it's just the first one that hasn't come apart in flight and killed it's crew (yet). Google for BD-10 flight test accidents to see what happened to his last supersonic design. The feathering design of SS1 leaves it with a major 'weak spot', the whole airframe is a 'moving part'. The control problems on the last flight show, the design is not without it's weaknesses.

    Wildfire will be a non event to watch the launch, since it's going up under a balloon to 80,000 feet. The airframe itself has not had an all up flight configuration live test yet, but, it's a relatively simple design, with little/no real aerodynamics involved, and no flying surfaces other than a couple stabilizer fins. Like SS1, it's using a hybrid engine, so the potential for a fuel explosion is little/none.

    If you want to watch things blow up, you are much better off waiting to go watch a shuttle being fueled or launched, should they ever actually do that again. With all that liquid fuel, it's just a big bomb waiting to explode. Both SS1 and Wildfire have potential for an in flight breakup, SS1 being a much higher potential than Wildfire simply due to the type of structures involved. In either case, the chances of a real explosion are virtually nil.

    That flying rock, I highly doubt that even a CAT 5 hurricane would produce enough wind over the wings to get the aircraft above Vs.

    Googling for shuttle stall speed turns up meaningless links, but, google for landing speed and you get this . Scroll down, and you'll find it's using 213 to 225 mph as touchdown speed, and it's likely a valid assumption the range depends on all up landing weight. Working backward using traditional 'airmanship' numbers, touchdown is approximately 110% of stall speed, unless limited by tires etc, so it's probably safe to 'guess' the shuttle stalling in the area of 180 to 190 mph. Again, this is all somewhat subjective, as stall is truely based on angle of attack, and since the shuttle is unpowered, hard to measure a 'level flight' scenario, but, it's pretty reasonable to assume it is incapable of gliding slower than 180 to 190 in a sea level atmosphere just based on it's touchdown speed.

    Another little detail, in order to have the wind 'pick up' the shuttle, it'll have to be nosed into wind, and set with the wings at the optimum angle of attack. A shuttle on the wheels is very distinctively 'nose low'. So, not only will you need a cat 5 hurricane, you also need Nasa folks to park it on a slight rise to get the angle of attack right.

    I think nasa can rest assured, a shuttle exposed to a cat 5 hurricane by 'just parking outside' is not going to suffer a blow over. It may take some damage from flying debris, but, it's not going to blow over. I believe the structure itself is quite capable of handling hurricane force winds assuming it's parked nose to the wind, it endures much stronger aerodynamic forces during landing.

    The launch facilities may be at risk to hurricanes, but the shuttles themselves, are probably safest parked out in the wide open away from potential debris, nose to the wind, and tie-downs are quite optional.

    I've never believed that using your laptop, game boy or mp3 player/walkman "interfered with the instruments", or whatever excuse they give you.

    They dont tell you it interferes with the instruments. The real reason is because it has not been tested and verified that it does NOT interfere with the instruments. The regulations on this point are very clear, only devices that are approved for operation during the takeoff and landing phase may be used. That doesn't mean unapproved devices are unsafe, it means they have not been demonstrated to be safe, and until somebody pays to take it thru the test procedures, it cannot be used.

    This goes way back to the early days of instrument flying. Landing approaches were based on the radio range, and direction finders, both instruments that are effectively am radio recievers. Shortly after the advent of the portable transistor radio, a few airplanes were lost during approaches. Eventually it was determined, these portable radios were using the same intermediate frequency (455 khz) as the navigation gear, and were causing interference with the nav gear. Pilots unknowingly flew airplanes into hillsides because they were in the clouds, couldn't see anything, and thier insturments were giving false indications. There was another incident in the 60's where a jet transport aircraft impacted a mile short of the runway on a precision instrument approach. Post crash analysis determined that an electronic device being operated in the passenger cabin was interfering with the instrument landing system, and causing bad indications in the cockpit.

    After this was determined in more than one occurrence, the rules for aircraft were changed to a proactive prevention style of ruleset. It matters not wether or not your device _may or may not_ interfere with landing systems. It only matters if it's been tested to prove it does NOT interfere. Unapproved devices are not permitted to be operated during critical flight phases.

    If you really believe that your ipod wont interfere, and you absolutely _must_ have it on during takeoff and landing, the solution is really simple. Just take it to a lab that does this type of emissions approval, and get an approval for it. It's going to cost on the order of $100,000 for the testing and certificate, but that's a minor cost when you balance it against the number of lives on board your average jet transport aircraft in airline service. The aviation world has learned the hard way, you must begin with

    #assume nothing

    and then you can build from there. If a device has not been demonstrated to be safe in the critical flight phases, you turn it off. If you absolutely _must_ have it on, take the time, spend the money, go to the lab and PROVE that it's safe. Until you've done that, you can turn it off.

    I've done millions of miles in the air, and seen my fair share of anomolies in navigation gear. I've dealt with the ignorant public that thinks they know better and wont turn devices off. One good thing about the new police state, it's kind of fun filling out the form with names of those folks to have them officially added to no fly lists. I hate ipods, and the ignorant attitude of folks that think they cant live without that contraption blasting mindless drivel into thier ears. You can rest comfortably knowing, I take great pleasure in adding a name to no fly lists when an ignorant ipod user wont turn the thing off for landing.
