For the record time in three days the target was Regensburg. This time the target was the Prufening A/C Factory. Twelve of our planes tacked on to another Wing and bombed Graz. Fifteen hit the target. Apparently the target was hit hard by all groups concerned. We hope so, for we paid a heavy price. Four of our planes failed to return. Two are definitely known to be lost over the target. Weather was very bad on the trip to base. Two planes, one form the 450th and one from the 98th, landed here. Four of our planes had to land at friendly A/D’s. Our fine stone building leaks in spots we discovered. Officers now eat in an officers mess and hope they have abandoned mess gear for the duration.
