"it is pertinent to examine the conditions and handicaps under which AAF planes had operated. never were more than fourteen B-17's over a group of targets at any one time, and even these failed to attack the same vessel simultaneously, thus further decreasing the existing slight probability of hits. Furthermore, most of the attacks were carried out by small flights of four planes or less per target, a number far too small to meet the requirements set by standard AAF doctrine.* Thus, the number of aircraft available fell far below the minimum demanded in order to achieve a profitable pattern for attaining hits upon even one carrier maneuvering at high speed, causing air commanders to feel that severe criticism of the B-17 performance was not altogether justified, for Midway was not a test of the bomber. They noted that the AAF had played no part in planning the defense of Midway, nor had it retained operational control of the few planes actually sent up to the island outpost; they noted, too, that critiques of the battle had indicated a tendency to rush the attacks upon the carriers at long ranges without adequate planning for co-ordination, with the results that the torpedo squadrons had suffered disastrous losses. Even General Hale had no advance knowledge of the composition of the enemy surface forces his bombers would face.
One of the most serious handicaps was the lack of adequate servicing facilities or personnel on Midway, where the combat crews not only flew long, exhausting, daily missions, but to a large extent were forced to do their own servicing and maintenance. Destruction of the powerhouse on Eastern Island by enemy bombing on 4 June further complicated this situation, completely disrupting the only available refueling system, thereby making it necessary for the tired crews to spend long hours servicing their planes from cans and drums, although in this task they were aided by marine ground troops on the island. A further factor was the rapid exhaustion of the crews of the combat planes in long 1,800-miles reconnaissance missions prior to combat; General Hale had protested in vain against the practice of sending out his B-17's against unknown targets, but he was overruled despite the fact that prior to the search mission of 1 June, his crews had not enjoyed seven hours' sleep in two days."
"* It is of interest to note that immediately prior to the Battle of Midway, Maj. Gen. Robert C. Richardson reported from Hawaii that a force of no less than 90 to 100 heavy bombers would be necessary to assure the probability of 7 per cent hits on an enemy force of five carriers. He based this figure on earlier bombing experience which indicated that even from the relatively low altitudes of 12,000 to 14,000 feet, at least eighteen to twenty planes would be required to insure 7 per cent hits on a single maneuvering surface craft, (Report from Maj. Gen. Robert C. Richardson to Chief of Staff, 1 June 1942.)"
"But the AAF B-17 had proved itself superior to the PBY in fulfilling the vital requirement of continuous tracking. Both types could search the sea; yet once the contact was made, it was the B-17 rather than the PBY which could stand up to strong enemy air opposition and cling to the contact. Hence Admiral King placed a bid for sufficient number of B-17's and B-24's for naval use in long-range search and tracking."
