Starship Wave eyeing a nice blue distant shiny planet ... never mind if they have the fuel and supplies to get there. Never mind if rationing should have started long ago. The planet is shiny and blue. Focus on that. To consider the fitness of the vehicle or its command is failing to see the big picture ... that distant shiny blue thing.
The irony is it is the stargazers that won't see the big picture. They won't take their eyes out of the telescope. Distant focus to the exclusion of everything else masquerades as big picture. Considering the distant object AND the ship, the path, and the command is somehow not seeing the big picture.
Deliberately seeing less masquerades as seeing more.
