Tourist - it's the standard NCO vs officer diatribe that one gets in the RAF. 'Navigators always get lost, are only there to carry the bags' vs 'Salt of the earth, only people on the ac who work hard'. It gets really testing (especially as I once spent 2 years as the only navigator on a sqn of pilots and crewmen), but you get used to it. One of the reasons why the crew room became a place to avoid.
You're very correct!
