phone call which took away the concentration of the controller leading to the fatalities.
The NTSB intial report clearly states the PA32 was transfered before the helicopter was airborne. The Teterboro controller did not know about the helicopter, could not see it on radar and therefore could not pass traffic information to the PA32.
Galactica Actual, could you please clarify what you mean when you suggest a loss of concentration of the controller led to the fatalities?
