The course gave each aquanaut an intimate understanding of the functions 

 and malfunctions of each system in the Mark X so that in the case of an 

 emergency, an aquanaut could think his problem through and apply the right 

 corrective action without endangering his safety. The written test given 

 the aquanauts at the close of their training detetmined their level of 

 understanding of the Mark X, The swimming portion of the training course 

 was primarily to observe the aquanaut and determine his proficiency in the 

 use of the Mark X. 



PROCEDURES 



The training program that gave the aquanauts a thorough understanding of re- 

 breather maintenance, functioning, and malfunctioning was designed with the 

 help of an on-site diving officer and the operations director. The water 

 portion of the course was programmed to allow the aquanauts to gain 

 familiarity with the Mark X while swimming and working with the unit. The
