Because you keep harping one specific incident, not the trend of an entire war. You're also speaking of an 'unescorted' bomber run, which you're highly innacurate on. The run was escorted for most of the way... you're being very selective of what you quote... here's what you didn't quote from the same article:
For hundreds of miles inbound to the target area, the B-17 bomber formations were attacked again and again by large numbers of Luftwaffe fighters. A Spitfire escort protected the aircraft over the English Channel. They handed over to fifty P-47 Thunderbolts who accompanied the raid as far as possible. Over Walcheren twenty Bf-109s attacked the escort fighters. German losses were five destroyed and four damaged while no U.S. planes were lost. At Duren, thirty Fw-190s attacked the bombers. Another twenty Fw-190s later joined the attack. During this battle, several B-17s were lost, as well as at least one P-47. German losses were six Fw-190s. At this point, the Thunderbolts had reached the limit of their range and had to return home.
The Schweinfurt run
was escorted... it wasn't escorted the entire way... there were three hours without escort for a run that lasted (from start to finish) for the better part of an entire day. The escorts did manage to keep most of the enemy off the formation for the majority of the run to and from the bombing run.
I can assure you, if the run was "unescorted" as you incorrectly stated, the fighter casualties would have
greatly outstripped the flak casualties... that's just a simple fact.
Most importantly, you completely neglected (for reasons I can only imagine) the CONCLUSION that was made in the same article you quoted, and what the whole article was about... THE IMPORTANCE OF ESCORTING A RUN! You don't develop long-range escort fighters to protect from FLAK you know... so if you're going to pick-cherries out of an article, do us a favor and let folks read the more important part of the article, like what I quoted above (about how well the run was escorted) and the logical conclusion of the article here:
The USAAF learned the importance of a fighter escort with sufficient range, recognizing the vulnerability of heavy bombers flying in daylight against interceptors. Such very heavy losses could not be sustained, and unescorted daylight bomber raids deep into Germany were suspended until 1944.
The conclusion of the article you quoted from clearly states they need long-range escort fighters... the reason is because of enemy fighters... the USAAF suspended operations beyond escorting fighter range until they had long range escort fighters... the reason? ENEMY FIGHTERS... you don't escort because of FLAK... you escort because of enemy fighters. The article didn't conclude they would suspend bombing because of FLAK, they said they were suspended because of enemy FIGHTERS... a conclusion you neglected to qoute.
Stop cherry-picking to support your cause... I read the same article, and it's clear what is stated... if there's one thing I know it's USAAF history. The Schwienfurt raid proved the whole point about gaining air superiority... it's taught in all Air Force Professional Academys.
Simply put, FLAK casualties will always outstrip fighter casualties if the run is either escorted or there are no enemy fighters... I'm sure most of the bombing runs over Berlin suffered more FLAK casualties then fighter casualties... that's not because FLAK was more deadly then fighters, that's because no fighters got through to the formation. In the case of Schweinfurt, the run was escorted most of the way and back again... casualties would have been much greater by enemy fighters if (as you incorrectly stated) the run was unescorted.
You're looking at a statistic and drawing completely wrong conclusions. The USAAF looked at the same results and decided to suspend operations because of enemy fighters, not because of enemy FLAK... are you saying your conclusions on the run are better then the top military generals of WWII?
