If someone has a medical condition then fine, but it remains for them to find a way to NOT require the need to piss about and faff around in an overhead locker.
Which is what this thread is all about, to give those of us with concerns options to plan for the event if it occurs (and there are some useful ideas).
It is possibly also to draw others concerns to the attention of various posters so that they can see that all is not easy for others
So comments like:-
I'm going to shove you out the way and get the hell down that slide !
Show a total lack of concern for others who are trying to plan ahead and are in the context of someone asking questions basically selfish.
(though not me I'm sure some would happily plant an elbow in your face if you start pushing and shoving which might slow you down)
At any time have I suggested I'll be rooting in a locker? NO
If I've got a plan it is to prevent that as I'm well aware of the need to get out and not disrupt the flow of folk, but still feel that in some circumstances a piece of hand luggage is needed, these are banned because of the risks, quite correct, so I'm trying to find a risk free (to all passengers and crew) means of dealing with this!
I don't know, is the answer to have a clearly marked small bag for the medical stuff, agreement with regulators etc. that these are allowed on slides and agreement from all airlines that it can be carried on in addition to any "one piece of hand luggage rule"
You tell me!
