Is all this sort of thing really about safety or is it about profits?
In the old days when videos came out we had the betamax v VHS ( or whatever). they were both touted as being the best.
Eventually betamax went to the wall leaving loads of people with useless kit that they had to bin. ( OK so eventually most went to cd's anyway, but at least its still relatively easy to play a video if you want to.)
Same thing happened a few years previously with in -car entertainment and tape players.
Now its one thing not being able to listen to your super8 tape or watch an old vid but it is a bit more important when the object is to miss an oncoming plane. Surely it would be better if one system was agreed and all the manufacturers concentrated on gaining their part of the market by good value reliable products.
With a new system coming out almost weekly ,it's natural for people to wait to see what comes out next week and that means no one is using the kit whilst waiting, so not much increase in safety there then, the manufacturers are not making the money to stay solvent, no good to them, and those that have taken the plunge and bought kit find it of little use 'cause they're the only ones flying in their neck of the woods with it and its not compatible with anything else and is about as much use as a three week old sarnie.
