Pah! You call those niche! How about flying a booster for the UK's crappy space programme in the Vulcan's bomb-bay from Lincolnshire to the Woomera rocket site, Australia, illegally crossing Indonesian airspace on the way, because they figured out that the Indonesians would probably not detect the Vulcan (early stealth) and if they did they had nothing that could intercept it. And then the whole Vulcan crew fell asleep for about an hour, while the plane carried on on autopilot. Strange but true - my Dad was the captain.
