Sue - sweet story. I expect any healthy and strong man to do the same. For them, carrying a fragile thin old lady that way is no match at all.

But if the disabled person is heavier or the carrier less strong then the Fireman's carry is the way to go. It isn't exactly a dignified transport method, but it is effective, ergonomic (for the carrier - not the carried!) and it gives you one free arm.

Everyone should know how to do a Fireman's carry.

That still doesn't solve the problem of evacuating disabled persons, does it? You can't really count on there being an ample supply of strong gentlemen to carry anyone in a wheel chair, can you?
