Very, very sad indeed,
Being a lowly PPL I need to gather as much information as I can, for the selfish preservation of my life, effectivly gaining experience of incidents from others, I know it is not possible to say why that Gazelle hit the ground, but it does look like the unfortunate pilot had little time to react to whatever situation arose in the way that the wreckage is contained into such a small area, I am not trying to be gory or even looking for any apportionment of blame , but would the picture shown on the previous post indicate a fast, low alt irrecoverable incident.
I hope you highly experienced pilots out there don't take offence at my question!
