ithinkso,
You may be pro 737 but you seem to sound anti OA.
For such an "insignificant operation", you're taking significant interest in it's petty activities.
I wonder why. 'Small things amuse small minds' comes to mind.
The ON/OA B737-2/3/4 throughout the last few decades have done a splendid job with the BNE-HIR runs. They've only it them for....let's see.....40 years.
When all is said and done, and everyone else had been and gone and had their fill, from fatcats to carpet baggers to wantok pollies and expat experts, from lean times to times of plenty, bird flus and pigs, from coups to roos on tails and economic blues, virgins and hazbeens, solair in despair, etc etc etc this little operation has seen it all and has defied and survived sometimes incredible adversities.
And this, without any prejudice. Just fact of history.
They will not, as you say, be going anywhere any time soon.
