Suppose you are flying to Innaminka from Brisbane you calculate you will only have 25 min remaining due wind after Thargomidah,. You overfly the Dig tree strip abut 40 miles out. Are you going to land at the tree or perhaps eat into reserves by 10 minutes or land at the tree and organise fuel and a drum pump from 40 miles away? (Bombers question to my partner: "you married to that guy? You like dogs? God bless him.)
