When Toyota can build a car that will never need a 'Recall', when BEKO can build a washing Machine that doesn't catch fire, when Microsoft can make a computer that doesn't crash and when Tom-Tom can make a GPS that doesn't send you down non-existent roads....maybe then I'd think about getting on a single crew long-haul airliner. In other words, never.
For goodness' sake, we can't even invent a toaster that can do 2 slices of bread with equal browning on both sides!
