Have the J* guys and gals considered who they will turn to if, god-forbid, they need to carry out an evacuation in Japan and accidentally kill someone?
The JPC, with no IFALPA affiliation is not going to be a lot of help. The JPC, with zero experience in these sorts of matters, is not going to be a lot of help getting the pilots out the jail where they will most certainly be put.
Whatever you may think of AIPA, there is a wealth of experience in those sorts of matters there ready to be tapped for its members. Something to think about.
