My name is David Tait - I'm an NSPCC Trustee and 'charity mountaineer' having now successfully climbed Mount Everest four times - in 2005, 2007, 2009 and 2011. I climb to raise both awareness and money for the many violated kids - one of whom was I.
We had been assured by the Katmandu Helicopter Company that the aircraft would be with us soon after 07:15, but in typical Nepali style, if finally clattered into view at the foot of the valley an hour late. This wouldn't have been too much of a problem were it not for the extreme cold.
I've arrived at Base Camp (5350m) - which marks the starting point of where I'll begin my true trip up the mountain. From base camp, climbers typically train and acclimate by travelling and bringing supplies back and forth through the often treacherous Khumbu Icefall.
The darker evenings have caught me unawares a couple of times recently. Fortunately, I've not been far from home and I've had access to lights for my bike so I've coped with relative safety. But being caught in the dark on the hills in Scotland is never a good idea.
