At this time FR24 reports the aircraft was not "diving" and was infact holding an altitude of 3500-3700 feet. The helicopter was consistently between 1,025 and 1,050 feet. Any thoughts on this? Based on the FR24 data they had ~2,500 feet of vertical seperation.
3. Last received data from the helicopter was at 12:00:46 (1000 feet consistent speed and heading with previous data). Last received data from the aircraft was at 11:59:44 (2700 feet (a loss of 700 feet in 24 seconds), with speed and direction remaining consistent with previous data. Generally speaking data from the heli was received every ~10 seconds. Data from the plane was received slightly less often but not by a large amount. Why was data received from the helicopter for another minute than the plane? I can only think of one reason - and if that was the case it msot likely wouldn't be reporting a steady alititude of ~1,000 feet.

Wealthysoup: Are you suggesting that the fix wing aircraft suddenly entered into an extreme dive, consistent with (for example) pilot incapacitation and/or loss of control plus total loss of electric power, consuming all of the 2,500' of carefully maintained vertical separation?
