5. Mr, Vetter (ONR) agreed to act as administrator for the project 

 and to try to initiate the next link in the chaia, which was to obtaim 

 permission for the use of two suitable aircraft. 



As a resxilt of this meeting the first operational plaa was put oa papar 

 (Pierson [1954]][, and the project achieved an air of reBpectabilitj eMiaaced 

 by the eagerness exhibited by the participants. Altitudes and baseliaes 

 were defined. Sources of stereo-analysis error were given, and error 

 magnitudes were estimated. A flying procedure was suggested. The misa^ 

 ber of pairs of photos which would be needed 'w^as estimated, and the 

 functions of the ATLANTIS were established. 



As soon as -definite plans had been set down the project weaat iiato- Mgh

 Laboratory, Boston University was productive in two ways. His assuraacss 

 as an e3q)ert photogrammetrist, that chancps for success were high fell on 

 welcome ears. Of more immediate importance, his disclosure fiiat tlie 

 French had achieved success with an FM triggering device waa eactreanelj 

 heartesaing because this was a critical point in the scheme. A paper hj 

 Cruset'T^1951] describing the activities in France along 'these liiaes, was 

 studied carefully by R. G. Walden, head of the WHOI Electronic Divisioa*, 

 and it was concluded that his staif could match and perhaps improve ti'.e 

 French instrument with respect to differences in triggering time between 

 cameras. 



The ground control problem was solved at WHOI with the discovery
