OK lads, what about the possibility of expanding the radar coverage so that these aircraft would not be allowed into the Class E airspace or anywhere near jet traffic unless they are positively identified?
Problem solved????
No I hear you say, then make it a requirement as sheep guts mentioned to install a secondary transponder for flights in class E airspace adjoining the major traffic centres.
And yes Sheep old son, I used to be based with the intrepid Capt Morgan!!!
