When your fighting in the air the pilots are fighting for the here and now, to sum up one quote they wanted to do their job and get back in one piece. Doing their job involved fighting the Spits defending Malta and destroying them. The quicker they could do it the quicker the Battle for Malta would be over and the safer they would be.
It doesn't make any sense to me to pace myself and go for a battle in the longer period. In almost any kind of battle, one important factor is to overwhelm the enemy and destroy them. This is particually important in a situation like Malta where you have the British on the defensive, spare parts are hard if not impossible to come by, workshops have been destroyed, there are no refueling facilities and it takes a fair amount of time to turn a plane around. Plus of course there are no reserves, everything that can fly must fight.
Germany had all these advantages, the reserves, spare parts, workshops, numbers, bombers, initiative, secure bases (occaisional raids but nothing like those endured on Malta) and still failed to destroy the Maltese defences. The question is why?
As fara as I can see Malta only had two adantages. Park who was probably the best defensive fighter commander of the war, and a surplus of pilots. As a result off the aircraft losses on the ground as well as in the air the pilots may have been fresher, despite the poor food and heavy bombing.
You will have twigged by now that I don't believe the Spit V to be any worse than the F4, not any better but a fair match. The Macchi 202 performance wise, didn't have to apologise to either of the other planes (why didn't they give it 2 x 20) it wwas just underarmed
My argument is that if the 109 was better than the Spit V then with all the other disadvantages then Malta would have fallen, it didn't fall and the spit couldn't have been any worse than the 109..
The only reason that I can see why the Germans failed is due to poor planning and poor tactics. Ju88's can fly across the whole island in minutes there was no reason for the German bombers to suffer the losses they did unless the planning and tactics employed were innadaquate.
