Because in the game, the concept of patrolling aircrafts only exists at sea, and the only aircrafts that are allowed to patrol are FTR and bombers with Air to Sea Factors.I can accept that rules interpretation. My only question is: why no fighter-to-fighter combats over land? Certainly air superiority is important there as well. Of course this is a game, and the rules can't always make perfect sense, but if fighter-only combats are possible at sea, it seems they should be allowed over land as well.
Over the ground, the only FTR to FTR battles that you can have are those that often happen when, after all bombers have been cleared to their objectives, the FTR keep on fighting each other. No obligation here, just a will from both sides to try to gain air superiority by inflincting more losses on the enemy than they suffer.
I also might point out that historically, the British invented the Circus Missions in 1941, just to challenge the Luftwaffe Fighters in the West. These Circus Missions involved a small number of light bombers (6-12 Blenheims, Bostons, ...) escorted by large numbers of fighters, often a whole Wing. The Brits had previously experienced that the usual Fighter Sweeps missions were usually ignored by the Luftwaffe fighters who suffered from numerical inferiority, so they tried adding some incensitive for the Germans to come to fight by putting bombers in the fray. This did not work really well until the Allies were able to mount real large scale bomber raids that the Germans couldn't ignore anymore.
