Yep, I don't think a 90 lb F/A is going to have much success against a lunatic hell bent on creating havoc.....
Rings back to the '3 man for safety' issues when the F/E was first put out to pasture.....
3 pilots is about the only way to help the issue....'someone' would have to bear the cost for this of course and the public generally prefers their cheap tickets!!
imho
