The Harrier, declared
When the ten teams published their provisional airframe choices, ours was the only one nobody else had picked. More than one person asked us if we had made a mistake. The Albatros and the Hawk are cheaper to run. The Falcon is faster. The Skyhawk turns.
But the Harrier can do something none of them can. When a hit against you costs exactly as much as a hit for you, being able to make a pursuer fly past you is a serious advantage. We declared the Harrier in September. The choice becomes official at the pre-season inspection, and we are already looking for a third airframe.
