| Well blow me down, there is a figure! I have been using common sense for 37 years. It tends to get a little bit windy to get out and measure 30 or 46 metres, not that I am any good at judging distances like that anyway, especially from a Boeing flightdeck (of all models!). The darn exhaust blows the tape measure to hell. Guess that's why the hair is thinning! |
