Should we have the RAF sub-let our aircrews out to the likes of Ryanair for a few quid?
Or should we perhaps rent out pongos out as nightclub bouncers, flogging dope produced from poppy crops which they so munificently oversaw when they patrolled Helmand? That sort of thing worked very profitably for the best part of 99 years in Honkers.
Should we perhaps funnel their pay and perks through the Caribbean? It works for upper echelon Duchies, such as those of Cornwall and Lancaster, which have a very lengthy history of booty-grabbing, particularly in that part of the world.
