Am I right when I heard the Jetblue had the VFR traffic in sight, they were cleared to descent to 3000 feet and the VFR was at 2900 feet, later on they said they respoded to the RA TCAS warning
Second question:
Can we learn a lesson here that things became too bussy for the controller because she was stepping on transmissions pushing/pulling the PTT switch too fast?
An accident never comes alone is a saying, so I thought when you notice stepping on transmissions can lead to this near deal?
Who can explain some more?
Without the radar tracks to go along with the radio recording it's not possible to fully analyze this scenario. There was a lot of radio traffic and a lot of traffic, and I'm not sure it's clear which of the targets caused the RA.
As far as the heterodyne you heard (the squealing sound where multiple keyups were going on) this obviously can happen on a busy frequency. The controller was not "stepping on transmissions" with the intention of cutting pilots out. But you have to understand that the controller's job is to, first and foremost, separate aircraft. A secondary task, and not unimportant, is to control that frequency. The controller needs to prioritize transmissions and communication on that frequency to aid in succeeding at goal #1 - to separate traffic.
It was simply a very busy time period in a normally busy sector.
