Due to the congestion on the ground approaches to the runways from/to the terminals, crossing active runways , etc there was mention of using stop/go red/green lights embedded in the ground at the busier airports, has anyone seen these, or already in use ?

For those that recall the C-119 flying boxcar, lost an engine about 20 minutes after take off. Everyone had a parachute on and we were told to tighten the straps and get ready for a possible jump, we were not paratroopers. Pilot decided he could make it back and aborted the jump, wow, sure got everyones attention, and then boarded another C-119.
