KAL 007, route errors, and civilian GPS access

Without the shootdown of Korean Air Lines Flight 007, when might its navigation error have become clear, and did the disaster directly create civilian GPS access?

The deviation might only have become undeniable near the aircraft's destination, the incident prompted route and safety changes, and wider civilian GPS use resulted from a broader commercial and policy decision rather than this event alone.

The crew's course error might have remained uncertain until the aircraft approached the Seoul area and expected landmarks or approach cues failed to appear. The shootdown led to changes in how the route was organized and monitored. Soviet defenses were operating in a tense environment shaped by earlier American RC-135 intelligence flights near the region, which helps explain the danger without excusing the attack. A later clarification rejects the idea that civilian GPS access flowed solely from KAL 007 and points to a broader decision to open the technology for commercial use. The flight's immediate safety consequences and the longer policy history of satellite navigation are separate issues.
