RatherBeFlying......the answer is easy, we need to have all birds fitted with Modes S transponders, TCAS, TAWS, 8.33Khz spacing and, of course, FM immune radios. This stopped the weekly carnage of GA aircraft having midair collicions with airliners which as you know was going on at an average of one per week for the last 30 years.
In fact, like the authorities did to GA, why don't we make the birds pay for it all themselves. If they don't have any money then they can deliver mail, or something, until they have worked up enough dosh. We can give them an exemption to operate without required equipment until they can afford it.
(Exemption = i'll contradict myself by allowing you to do what I just told you was unsafe because I can generate more money for the industry like that, but we still need the rule for those who can afford it)
