Vrystaat, taking what you say into account - just my thoughts:
yes he was going at full power, but that does not mean, that he was fast - you know how a 210 flies on the wrong side of the drag curve and if she doesn't want to fly due to weight and density altitude - what can you do ? If you start pulling like you said anybody would, you will just end up in a stall. The only way to get out of the mess is lowering the nose to get speed, but that too was probably not possible due to the terrain. Maybe he was in a stall while hitting the lamppost and the tree, dropping steeply into the from there ground or what do you think ?
The company and its sister company have been suspended from operation until further notice. Read that in the news a few days ago.
