In 1956 when those things went up there, we had to do all the work forward because it was impossible to send the signals back. The ability did not exist. The number of people you could consult was smaller because there were 250 people there and that was it. Now that we're doing it back here, we can draw on everybody in the Canadian Forces intelligence community. The human interface is not the same as talking on the phone, so the ability to analyze is better.
Technology was valves and vacuum tubes and stuff back in the fifties, and it has obviously advanced considerably since then. Our ability to collect and process signals and figure out what they are is much better.
Conversely, the ability of any target to hide its signals and make them difficult to understand is much better as well, so it's a continuing.... Communications information technology advances by leaps and bounds, and it has advantages and disadvantages for both sides when it does that.
