A large passenger aeroplane

"If you could be a bird, looking downwards from the skies, and a portion of the covering of an enormous passenger-carrying aeroplane were removed, this is what you would see. Note the three powerful engines, under the dual control of the pilot and navigator, and observe also that this great air express is fully equipped with wireless. Moreover, a steward is carried who serves refreshments during the journey much as would happen on a long-distance railway train"
