Hi guys,

Perhaps a good time to throw a few facts and onsite speculation into the mix.

Facts first:
- It was not my plane.
- The radio was set up with failsafe.
- The pilot was having some retract problems and all the retract movements you see in the video were made by the pilot.
- The plane was not flying at altitude, but basically at sea level.
- It was not hot, the temp was around 18c.
- The pilot is well experienced in jet flying - I've known him since 2004 when he had been flying them for some time already.

The onsite speculation:
- After the crash there was a conversation, in my presence, between the Viper pilot and another pilot that concluded the following situation.
- The second pilot said that at the exact time of the incident, he was switching on to fly his own jet. The radio would not bind.
- Both pilots were using JR 2.4 Spectrum equipment.

Therefor as the person, posting the video on YouTube stated in his comments - suspected radio interference or failure.

Cheers

Jan
