EXPERIMENTAL FLIGHTS WITH THE ORIGINAL LANGLEY 



AERODROME 



The trial flights with the original Langley aerodrome (built 1898- 

 1903), which were begun in May, 19 14, under the direction of Mr. 

 Glenn Curtiss, to determine whetlier the machine was fundamentally

correct in design and construction, were continued in 1915 at Lake 

 Keuka, New York. 



Toward the end of February, 1915, the machine was mounted 

 on three elastic skates preparatory to launching it from the ice on 

 Lake Keuka, with its original motor and as nearly as possible in its 

 original condition. When thus assembled for flight it weighed 

 without pilot 955 pounds, including five gallons of gasoline and the 

 necessary oil and water. The aeroplane frame and wings were on 

 March 2 taken on a tug boat 12 miles down Lake Keuka to where 

 the ice was thick, and placed upon the ice under the brow of a wooded 

 hill whose shelter made it easier to wing and unwing the machine 

 in the wind.
