Radar tracks will be very interesting. My totally uninformed guess is
we will learn the swing wing as assending into the path of the
Cherokee 6. What I've read is the 6 flew into the 'copter -- be
interesting to see what the NTSB finds and as importantly recommends
so as to not have this happen again.

I'll remind readers the FARs say the aircraf, t being overtaken has
right of way of the overtaking aircraft and at tabout the same
altitude the airplane on the right has right of way.

You can see the radar tracks on the following site:

If you start at about 11:50 AM, you can see all the aircraft in the area.
(Select the date and time, click on "Normal" then click on "Start". You
need Java, and it will take a moment to start, so be patient.)

There are northbound aircraft at 1400, 1900, and 4000 feet. They appear to
be an experimental, an Embraer, and an Airbus from the registrations and
flight numbers. You can see the helicopter rise into the path of the Piper
Lance, which approaches from the northwest at 1100 feet. The helicopter has
an airplane symbol rather than a helicopter symbol. Collision at about
11:53 AM
