In November 1916, he was accepted for a transfer to the Royal Flying Corps and was shipped to the United Kingdom for flight training. Graduating as a pilot, he was commissioned as a second lieutenant and posted to No. 45 Squadron RFC in France during October 1917; two months later, the unit sailed to the Italian theatre. Howell spent eight months flying operations over Italy, conducting attacks against ground targets and engaging in sorties against aerial forces and he was credited with shooting down a total of nineteen aircraft. He was awarded the Distinguished Service Order, the Military Cross and Distinguished Flying Cross. He was posted back to the United Kingdom in July 1918. In 1919, Howell was killed while taking part in the England-to-Australia air race. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
