I sometimes wonder what might have been the plight of Apollo 1 in 1967, if Intercept protection had been a reality.
Jan 27, 2016 marked the 49th anniversary of the fire that killed the 3 astronauts of what would have become Apollo 1. The fire shocked a nation, put NASA on notice, and became the worst disaster for the US Space program. That is, until Jan 28, 1986 when the Challenger exploded just 73 seconds into its flight.
