C.F. (Charles) Pollock made several flights by balloon across the English Channel, at least one flight across the Irish Sea, and on two occasions he took part in the Coupe Aéronautique Gordon Bennett. His victories included the International Balloon Contest from Hurlingham and, for Mrs. John Dunville, the Hedges-Butler Challenge Trophy. He was awarded the Royal Aero Club's silver medal in 1911.
Two of his first flights across the English Channel, from Britain to continental Europe, were in 1906 and 1907. The flights were in the February of each of those years, and the winter weather brought the north winds which made the flights possible. On 3 February 1906 C.F. Pollock flew with Mr. Dale, a fellow member of the Aero Club, from Wandsworth in the balloon Vivienne III to the French coast near Dieppe. On 21 February 1907 he piloted the Hon. Mrs. Assheton Harbord in her balloon, the Nebia, from Chelsea to Stavelot in Belgium. The 1906 flight took 3 hours and 20 minutes but the 1907 flight lasted over 10 hours. Both flights landed in snowstorms.
C.F. Pollock's entries in the Coupe Aéronautique Gordon Bennett were as co-pilot to Professor A.K. Huntingdon in the balloon Zephyr in September 1906 and as co-pilot to John Dunville in the balloon Banshee in August 1908.
In May 1908 C.F. Pollock, in the balloon Valkyrie and accompanied by the Hon. Mrs. Assheton Harbord, Miss Moore-Brabazon, Mr. D. Bingham, and Mr. R.A. Colville, won the International Balloon Contest from Hurlingham by landing one mile south of the goal of Burchett's Green Inn, three miles from Maidenhead.
In December 1908 John Dunville, C.F. Pollock, and Philip Gardner won the Lord Northcliffe Cup by flying the balloon Banshee from Chelsea Gas Works to Crailsheim, near Stuttgart in Germany. In February 1910 John Dunville and C.F. Pollock flew across the Irish Sea in the balloon St. Louis. The flight took off from the Dublin Gas Company in Dublin and landed at Birtles near Macclesfield, Cheshire.
C.F. Pollock flew Mrs. John Dunville in Banshee II in at least one of the flights in which she won the Hedges-Butler Challenge Trophy (1912, 1913, 1914). Philip Gardner was a passenger.
In the First World War he served in the Army as a balloon instructor.
