Yes same guy. Good book to read I can recommend it.  Author Ben Hellwarth.

In 1959 he and another guy did a free ascent from a USN sub in 320ft wearing only mask and a Mae West, they pressurised the escape trunk, breathed hp air, no sign of narcs and opened hatch. Inflated vests, as soon as they hit the ocean they started exhaling, they rose at around 6ft/sec, they broke surface 50 secs after leaving sub.

> Exercise Sorbet Royal
> A NATO exercise, Sorbet Royal in May 2002 (Cohen 2003), demonstrated the effectiveness of the system when four crewmembers and five others from Denmark, the UK and USA, both men and women, donned SEIE suits to simulate an escape from the Swedish submarine Vastergotland, down 115 feet off the coast of Denmark. The submarines escape tower had a four to six minutes recycle time, (determined chiefly the time it takes to drain the flooded tower) but they used a 15-minute interval for this demonstration. The exercise worked as briefed, with 18 seconds required for the pressure equalisation phase, the pressure doubling roughly every four seconds or so, and nine seconds required for the ascent. Rescue units, including a decompression chamber, were waiting in smooth seas on the surface.
