A while ago, flying into JFK, a mate had a light a/c vectored right across him when he was on the ILS. He got a TCAS RA.
He filed an airmiss report and an incident signal - as his company require.
Some months later he asked the Chief Pilot for feedback on the event.
He was told nothing had been heard back, and that it is common to have no response from the US to such reports.
Why so?
