I managed to get to the pole in 29 minutes and 33 seconds. I could have done it a bit faster, if I hadn't had map view shenanigans and hadn't overshot the pole a few times. And I need to detach the external fuel tanks earlier to reduce drag. I think I will be able to beat the record next time, but for now I'll settle for second place. I did use the fixed camera mod, but the plane is all stock otherwise, so I think it should count for 'stock' category. Have some images:
