I’m somebody else: as far as I know, 66 (or rather 666?) is deemed to be the Devil’s number. If you want my own interpretation of this, here you are: you may know the number 69 as the utterly simplified icon symbolizing mutual cunnilingus – so 66 would mean intercourse between male homosexuals (which in a number of US and Islamic States is still considered as satanic – yet any penetration from behind, be it heterosexual vaginal, will do as an explanation for psychorigid puritans… unfortunately enough for them, the missionary position cannot be represented by Arabic numbers).
This is of course well off topic, exept for the fact that the US marines got f… up by the kamikazes… (if not by their own fleet commanders)
It seems that 9-11 was also a date choice in relation with a precedent (I found this on the web and stored it away in my archives, but don’t ask me to dig it out as there are much more important facts and indications to be assessed).
@ Raguleader
Thanks for the precious expert information… president Bush too is an expert: he has just given green light to the implementation of ADS-B (Automatic Dependant Surveillance-Broadcast), which is no more based on radar but on the GPS to determine not only the position but also the intent of all aircraft, thus projecting on every pilot’s LCD screen the same picture as was to date only available to the ground-based air traffic controllers.
Note that the adjective ‘Dependant’ is a sort of a hoax, since this so called New Generation air traffic management system virtuallay supports totally independent operation, i.e. independent from the several hundred ground based control stations planned over the next three years to ensure coverage of the whole US and Canadian territory. So Bush may not even be aware of the true vocation of the system, i.e. the safe independent navigation of vast numbers of PAs.
Every pilot will tell you that piloting is easier than car driving – but this is not the point. The difficulty is to comply to the complex rules and protocols of ground-based air traffic control. Yet this can be fully automated. Currently the main occupation of modern airliner pilots is checking and surveying the automatic procedures of their aircraft – they could basically let it fly by itself from take-off to touch-down, yet they mostly prefer not to loose their skills by taking over the controls during these crucial phases.
If you plan to come to Switzerland (and if you have children), go to visit Lausanne with its fully automated metro! Or would you maybe not let your children have a ride in the front compartment where there is no conductor?
Now you may object that a train is riding on hardened steel rails. Ask any computer specialist about the possibility of projecting virtual electronic rails into the airspace. Not only will he confirm that this is quite possible, but also that there may be millions of such virtual rail-tracks calculated in real-time by the on-board computer of every aircraft with respect to all other aircraft within a critical range, so that never any one of these virtual rails will level-cross any other.
Remember the mid-air collision above Überlingen in southern Germany: the Swiss Skyguard operator told the Russian pilot to descend, whereas the TCAS (Traffic and Collision Alert System) of the aircraft instructed him to go up – had he obeyed his on-board avionics… (I let you complete, otherwise some moderator my remind me that if wishes were horses, then beggars would ride). The operator was stabbed to death later on by a Russian man who had lost his wife and two little daughters in the crash.
Don’t be ashamed, I experienced this reaction in almost exactly the same wording (with sometimes *falling down like stones *instead of mid-air collisions) from all types of persons I tried to get acquainted with my vision, including highly educated engineers…
You should know by now that navigation will be fully automated and hence the risk of collision drop to a residual figure versus road collisions (with virtually no attention required from the pilots, whereas on the road the least lack of attention might immediately have fatal consequences). Extrapolating from the above example of the Lausanne metro, you may even imagine tiny aircraft for kids…
Yet you should keep in mind that the PA could not be a helicopter because this rotorcraft has a series of intrinsic redhibitory snags and shortcomings:
[ol]
[li]high instability in the horizontal plane[/li][li]strong (aero)dynamic assymetry at cruising, resulting in[/li][li]prohibitive noise generation and[/li][li]excessive fuel consumption[/li][li]asymetric control response due to the gyroscopic inertia effect of the main rotor (although this is automatically compensated in modern helicopters)[/li][/ol]
Don’t believe either in the tilt rotor aircraft, as it cannot autorotate, nor in the Groen Brothers’ Rotodyne concept, as this is known since 50 years as being extremely noisy (because of its blade-tip ramjets for take-off and landing) and relatively slow (the Fairey Rotodyne never exceeded 350 km/h).
The only potential competitor against my concept may be Sikorsky’s X-wing announced for 600 km/h top speed, yet it still bears all the other typical shortcomings of the helicopter, especially the high instability in the horizontal plane. The helicopter is indeed comparable to a wine glass on a wet table: the least inclination makes the glass slide away fast in the direction of inclination; whereas it has excellent reactivity in the vertical axis through collective blade pitch variation.
My concept has the same reactivity in all spatial directions as the helicopter has only in the vertical axis. This is crucial for reduction of relative distances between aircraft in automated flight within a densely crowded airspace, including situations where the (yet to be written) distributed intelligence interactive protocols will have to command a slowdown or even a full stop (with consecutive vertical descent) of every aircraft within the critical area.

I brought up this supposition as a reminder of the current topic – so why should I waste time going on guessing what the past could have been if…? There is much more to gain from projection into the future of the perspective of the advent of massively widespread individual aeromobility, i.e. the transfer of road traffic into the airspace, which would enable the planetary mobilization of the civil society against those who have managed to achieve global air superiority with their relatively small number of supersonic fighters/bombers.
Imagine a myriad of wasps and bees (each carrying a sting) against a bunch of falcons and eagles…
