G'day Jabba,
Don't be suprised by the pilot being nabbed at 8 am. That's exactly the reason why cops set up RBT's early morning to catch people having a night out, getting a cab home at 4 am, have 3 hours sleep and drive to work in the morning thinking that they have slept it off. They could be four times over the limit still. I am not an expert but I think it takes an hour to wear off .01 of alcohol in your system after a big night out.
I think the old " 8 hours from bottle to throttle" is way out of date. I have been there, done it,..... and never do it again.
