56:19 Right. Well, Jack, First, let me just say, you brought up about ROIC, and I'll expand a little bit about on the remarks I made earlier there. We're obviously referencing to our WACC when we compare our ROIC, which we put in the seven percent to nine percent range, which I think is consistent with what we see in many of your analyses. But when it comes to the ROIC itself, there are a number of different approaches and methods that practitioners use, so this tends to be variability in the absolute as well as the comparative measurements, but that said we're revisiting the various aspects of that so that we can maybe expand the context around our discussion of the topic, but I will say regardless of how you calculate it, our ROIC does remain above our WACC. 57:12 So, since you asked about the LTI plan, look, I am not going to speak on behalf of the Board, but I will give you some context around partly about what I mentioned two, three months ago. So, again, we had record earnings in fiscal twenty one amidst the unprecedented global pandemic and delivering life-saving vaccines around the world. And we’ve talked about the radical changes in supply chains, customer expectations, and all that, so we did indeed accelerate purposefully some investment opportunities for capacity expansion and of course the replacement of the aircraft I mentioned before. So, as I did specifically say on the June call, the FY twenty two to twenty four LTI plan was eight percent to account for these opportunities, and that target is below our historical capital intensity. Fiscal twenty one was seven percent, but that was the lowest in ten years. So, again, there's absolutely a focus on returns, and I think that we will continue to address your considerations there, and I would also highlight because there was the question earlier about ground and investment there, and we're making returns there. 58:41 And we talked a lot about how we're utilizing our assets differently, more efficiently, vesting in smaller units of capacity. We got the one single hub, but there’s no other hubs on the drawing board if ground can generate a higher ROIC at different margin levels than it did probably eight, nine years ago. So, again, that absolutely factors into how we look at these things.
