took some time for the observer to accustom 

 himself to the image received, for it was, in 

 effect, as if he were standing in the center of 

 a radar screen and seeing everything in 

 front, in back, above and to the sides all at 

 once. Corrective masking shades were in-

 ward view which helped the newcomer to 



orient himself. The seated observers each 

 had a telescope-like object through which to 

 view. The top dome was later moved forward 

 on the bow as shown in Figure 9.31. 



Even the "best view" in many vehicles is 

 not 100 percent effective, because the posi- 

 tion the scientist or pilot has to take to get to 

 this view may be awkward and inordinately
