Inbound to 2RN
Last Tuesday evening, around 1900 LMT, SY Radar was getting more than a little concerned - an inbound a/c to 2RN was catching another inbound to 2RN, with a closing speed of 60 kts(by radar). The rear a/c didn't seem concerned, could have changed altitude, or slowed down, but didn't. Radar controller ended up calling "traffic alert". There but for the grace of God went another incident. Viz was below average with mist and haze. Rear pilot VH-PG? didn't seem concerned then or later. What are pilots being taught these days? (I wasn't in either a/c)
