Simon served in the RAF for 12 years as an aircraft airframe maintenance engineer. After leaving the RAF, Simon moved from aircraft maintenance into aircraft design. Simon does have gaps in his resume but is not prepared to talk about them. "Some jobs are of a sensitive nature," is the best response that one can gain when he is questioned. Simon is also an accomplished pilot and motorcycle rider. Simon has, for years, an avid interest in all things technical, especially in new design and the technology of tomorrow. Simon wrote his first book in 2011.
