Sorry about that NR, a small extension indeed might have done the trick, a weak link/plug somewhere in the cord might have done too.
This also very noticable during dunker training when you forget to unplug and after doing everything according to procedure, you find yourself stuck to the machine because of your helmet.
When seconds count this is definately something you don't want to happen.
Every trip I make sure that my (curly) cord is not tangled up in my belts or stuck behind something that might stop me of getting out in a hurry.
Just my 2 cents.
