Sydney Vincent Sippe
" ...Croydon Advertiser about the first "flight" made in the borough — actually in the hamlet of Addington. The aeronaut was Sydney Sippe, who a few years later was to raid the Zeppelin sheds at Friedrichshafen in an Avro 504. The experiments were made in 1910, jointly by Sydney, his brother Arthur H. Sippe, and one James Jensen. After 50 years the details have been recorded for the first time, together with the claim that this aeroplane was the first in the world to be made of steel tubing — a claim which, I feel, would be difficult to substantiate."

April 2nd 1912 Sydney Sippe flew the Avro D from Barrow dock successfully. First flight from seawater in Britain.
