vertical twin jet... military eight jet... I just love it when people thing they are hiding something from you... what else could we have? Double rotary, Supersonic passenger carrier (anyone?)
... and also apologise to all those impoverished ATCOs out there whose employers can't/won't afford 21st century equipment... to think we thought ours was the worst and we were lagging behind on the technology stakes. You'll be telling me you still use chinagraphs next!!!!
Sorry I digress
