I've have often wondered why the the pax belts ain't the same as the f/d crew fit. Hey we all drive cars, and can 'click' the seat belt. 250-0 knots waist only restraint will/might/probably cut one in half in the crash position (worst scenario) I would rather take my chances, arms bent on the rear of seat in front of me.
It's a total sham why waist/cross chest belts are not incorporated on a/c as in cars. Knowing that the vehicle industry has carried out more exhaustive tests on passenger survivability.I wonder why just waist restraints were opt for in a/c?
