You would be impressed, wouldn’t you, if Air Mail Pilot told you that just two weekends ago, a four-year-old boy climbed the highest mountain in Wales? You’d surely be even more impressed if reminded that this ascent took place not, say, in balmy June but rather in late November, in the wake of a major snowstorm, when the weather was still raw and windy. But here’s the most impressive thing of all: the boy made the climb on a prosthetic left leg.

Albie-Junior Thomas, who lives in the small town of Holywell, in Northern Wales, was born with a condition called fibula hemimelia, in which all or part of one of the major bones in the lower leg is missing. In Albie-Junior’s case, this resulted in a below-the-knee amputation when he was just 15 months old.
