White is Cheap. Do you know white is the cheapest of colours for flight designers? White colour keeps the weight of a flight light while other bright colours would increase the weight of a flight from 273 to 544 Kgs.
As the weight of a flight increases, more fuel would be required. Further, 544 Kgs is equal to 8 passengers. This valuable information was once provided by one of the authorities of popular Booeing planes.
