The tow pilot did show up late, the flight was somewhat shortened by incoming overcast but nobody asked me to take my shoes off.
Flying gliders is very satisfying.
...more precisely General Aviation and on an even narrower scale gliding (as in flying sailplanes) already has such a system. It's called Flarm (on Wikipedia) and was primarily introduced to avoid midair collisions between gliders as well as between gliders and obstacles such as powerlines in montaineous areas.
It's true P2P and works like: GPS locates itself, beacon (think garage door opener channels) sends position and some other data, receives the same from other gliders, predicts trajectories and gives alert if collision is possible. The raw number of units on the (ha!) air at the same time in the roughly same spot is rather low compared to cars. Of course you still need to look out... Openness of the standard has/had some issues, but i am not current on this one.
Sir,
your post suggests that you work as a professional (as being paid) pilot and as such should have at least a basic understanding of physics me thinks. May i point out to you that nothing will ever change the weight of a cell phone, brick, elephant or else as long as it stays in proximity to the earths surface. You are probably talking about the phenomenon of inertia which is directly proportional to an objects mass.
Oh, and please explain to us why there can be any significant danger from flying objects the size and mass of a mobile phone during a crash compared to the inherent shortcomings of the simple lap seat belts provided.
The only thing i can stand less than security theater is the people who actually believe in it.
Either you're totally kidding or insane. I'd bet my ass that (aerospace grade !) fiber is at least as expensive as the copper wires already in use. The price of copper or any other raw material like it can't ever measure up to production, quality testing etc. associated costs.
Furthermore i'd supect that it'll be much more difficult to design, produce and use properly working connectors between the different parts of the aircraft with optic fiber. IMHO it's not practical to run every length of cable/fiber uninterrupted point to point.
Those who can, do; those who can't, write. Those who can't write work for the Bell Labs Record.
