Well, I don't know how to see Ocelot before he hijacks the Ray, but a secret in MGS1 is:
*MAYBE SPOILERS*
When Meryl is dressed up as the guard and she goes into the restroom, if you follow her fast enough before the cutscene, you can see her changing out of the guard outfit and into her regular clothes. But, the minute you catch her, the cutscene comes up, so you can't do much after that. Not trying to be perv or anything, just thought this was a neat little secret.
