The results, said Jodrell Bank Director Sir Bernard Lovell, were "the most sensational pictures we have ever received...
...NORAD officer with a significant combination of symbols built up on his console can transmit his "display" to any other console screen in the center or, within seconds, have it projected on the large screen for everyone to see.
