NS Safety improvements?

[FrustratedFormerFlie]

OK, so,

1. Check in
2. Draw Immersion Suit etc
3. Don Immersion Suit etc
4. Oops, they've shut the door of the PFB room - and only opened a flap the size of the smallest emergency exit on the type I am to fly.
5. If I get through the cat flap, happy days. If I don't, head back to the (onshore) gym

Might sound harsh, but its a whole lot less harsh than finding out the hard way (ie in a ditching) that you dont fit - or worse, finding that your exit route is blocked by said lardy boy

Of course if introduced overnight, a significant percentage of next day's pax would be 'beached', so stand by for pleas for 'sympathetic/progressive introduction' of system from employers and emplotyees alike!
