Our task group was thirteen bombers. One such bomber could have carried all the dust needed, but it was split up to insure most of it, at least, reaching its destination. I had fetched forty percent more dust than Ridpath calculated would be needed for the mission and my last job was to see to it that every canister actually went on board a plane of the flight. The extremely small weight of dust used was emphasized to each of the military observers.
We took off just at dark, climbed to twenty-five thousand feet, refueled in the air, and climbed again. Our escort was waiting for us, having refueled thirty minutes before us. The flight split into thirteen groups, and cut the thin air for middle Europe. The bombers we rode had been stripped and hiked up to permit the utmost maximum of speed and altitude.
Elsewhere in England, other flights had taken off shortly before us to act as a diversion. Their destinations were every part of Germany; it was the intention to create such confusion in the air above the Reich that our few planes actually engaged in the serious work might well escape attention entirely, flying so high in the stratosphere.
The thirteen dust carriers approached Berlin from different directions, planning to cross Berlin as if following the spokes of a wheel. The night was appreciably clear and we had a low moon to help us. Berlin is not a hard city to locate, since it has the largest square-mile area of any modern city and is located on a broad flat alluvial plain. I could make out the River Spree as we approached it, and the Havel. The city was blacked out, but a city makes a different sort of black from open country. Parachute flares hung over the city in many places, showing that the R.A.F. had been busy before we got there and the A.A. batteries on the ground helped to pick out the city.
There was fighting below us, but not within fifteen thousand feet of our altitude as nearly as I could judge.
The pilot reported to the captain, "On line of bearing!" The chap working the absolute altimeter steadily fed his data into the fuse pots of the canister. The canisters were equipped with a light charge of black powder, sufficient to explode them and scatter the dust at a time after release predetermined by the fuse pot setting. The method used was no more than an efficient expedient. The dust would have been almost as effective had it simply been dumped out in paper bags, although not as well distributed.
The Captain hung over the navigator's board, a slight frown on his thin sallow face. "Ready one!" reported the bomber.
"Release!"
"Ready two!"
The Captain studied his wristwatch. "Release!"
