P-3 crews are pretty tight, especially on Det/Deployment.
We can't usually spend time with maintainers due to the fact that they can only work on the plane while it is on the ground, which also happens to be when we can go out.
My FE was basically another JO in the plane, but once we were out of the air, all the proper customs/courtesies were never lacking.
I've seen a few crews take it too far, but that was rare. We just didn't really have a chance to hang with MX.
One notable exception was a ten day det to Masirah I got to enjoy. We took one plane, my crew, an IS, about 9 MX and an O-4 to "liaise" for us.
Pretty much all our time off was shared as they had the plane put to bed about the same time we were done with the PMP. Had a great time, shared quite a few beers with E/O alike and the Omani General that ran the base was nice enough to open the O-Club for all of us.
