Possible near miss between DAL 757 and Falcon 2000

I've posted this already on airliners.net forums and only just thought to post it here for you guys as well.

Can't be bothered typing it all again so will just copy and paste my post to a.net.

I was listening to New York oceanic 6577 yesterday (Jan 28) and picked up some transmissions between DAL384 (N721TW) and Falcon 2000 N236QS which may be of interest to some.

The archived audio files can be found courtesy of liveatc.net at the following links :

The dialogue starts just prior to 1642 where N236QS calls NYC to advise that they've received a TCAS alert at FL410 and climbed to FL415 to avoid. Shortly after, DAL384 calls NYC to advise that they too have received a TCAS alert at FL400 which initially responded by climbing but then changed to descending to FL395 once they had the Falcon visual.

According to flightaware.com, N236QS was southbound on L454 at FL410 from Washington IAD to St Thomas STT, and DAL384 was northbound on L454 at FL400 from Georgetown, Guyana GEO to New York JFK.

There's a break in the conversation from around 1645 to around 1653 where it resumes again and NYC Center is phone-patched through to speak to the DAL flight. There are no new developments as such, as both flights confirm that they were at their assigned flight levels, but the DAL says he will "filing some documentation about this" as he wants to know why the TCAS initially had the plane climbing into the path of the bizzer instead of descending. The phone-patch ends just after 1700 with NYC giving the flight a landline number to call upon landing.

This area has no radar coverage as such as it's oceanic airspace (known as WATRS - stands for West Atlantic Route System) and basically covers the area from 60W westwards to the US east coast. Position reports are passed to NYC ARINC on HF who then relay them to NYC Center.

Perhaps of interest to some.

Think the links are broken...  It looks like the file name was shortened, and even in the link, it has the literal "..." in it where something shortened it.
