After a lot of good and careful planning, Equestria's greatest invention is ready to go: Fast Aerial Transportation of Pony Lot and Neighboring Equines, or FAT PLaNE, a wonderful aircraft which is commodious and light at the same time. Surely, this splendid innovation by Equestria's never-failing two expert inventors will revolutionize aviation more than anything else. With the blessing of Princess Celestia herself, and with the two most experienced pilots who are definitely suited for the job, safety is guaranteed for the freight and passengers. And they are absolutely not suffering from either aerophobia or ophiophobia. For that matter, security risks and/or snakes are positively not a problem here.
