with an assumed fairing length of 200 feet, the load at the

or about 0.5 percent of the length. In actuality, the fair- 

 ing elongation will be less than one-half of one percent of 

 its length because of the assumptions previously mentioned, 

 and so it was concluded that 200-foot sections of fairing 

 should tow satisfactorily.
