Twenty-seven minutes later, Dennings gazed past the beating windscreen wipers. The rain had increased, and he could only see two hundred yards through the wet gloom. Both feet pressed the brakes as he ran the engines up to 2,200 rpm's. Flight Engineer Sergeant Robert Mosely reported number-four outboard engine turning over fifty revolutions slow. Dennings decided to ignore the report. The damp air was no doubt responsible for the slight drop. He pulled the throttles back to idle.
In the co-pilot's seat to the right of Dennings, Mort Stromp acknowledged the control tower's clearance for takeoff. He lowered the flaps. Two of the crew in the waist turrets confirmed the flap setting.
Dennings reached over and switched on the intercom. "Okay, guys, here we go."
He eased the throttles forward again, compensating for the tremendous torque by slightly advancing the left engines over those on the right. Then he released the brake.
Fully loaded at 68 tons, Dennings' Demons, her tanks filled to their filler caps with over 7,000 gallons of fuel, her forward bomb bay holding a six-ton bomb, and carrying a crew of twelve, began to roll. She was nearly 17,000 pounds overweight.
The four 3,350-cubic-inch Wright Cyclone engines strained at their mountings, their combined 8,800
horsepower whipping the 16.5-foot propellers through the wind-driven sheet of water. Blue flame erupting from exhaust manifolds, wings enveloped in a cloud of spray, the great bomber roared into the blackness.
With agonizing slowness she picked up speed. The long runway stretched out in front of her, carved out of the bleak volcanic rock and ending at an abrupt drop eighty feet above the cold sea. A horizontal bolt of lightning bathed the fire trucks and ambulances spaced along the runway in an eerie blue light. At eighty knots Dennings took full rudder control and advanced the right engines to their stops. He gripped the wheel grimly, determined to get the Demons in the air.
Forward of the pilots, in the exposed nose section, Stanton the bombard
ier apprehensively watched the runway rapidly diminish. Even the lethargic Stromp straightened up in his seat, his eyes vainly attempting to penetrate the darkness ahead for the change in black where runway ended and the sea began.
Three quarters of the runway passed, and she was still glued to the ground. Time seemed to dissolve in a blur. They all felt as though they w re flying into a void. Then suddenly the lights of the jeeps parked beside the end of the runway burst through the curtain of rain.
"God almighty!" Stromp blurted. "Pull her up!"
Dennings waited another three seconds, and then he gently eased the wheel toward his chest. The B-29's wheels came free. She had barely clawed thirty feet out of the sky when the runway vanished and she struggled over the forbidding water.
Morrison stood outside the warmth of the radar but under the downpour, his four-man staff dutifully standing behind him. He watched the takeoff of Dennings' Demons more in his mind than his eyes. He saw little more than the lurch of the bomber as Dennings thrust the throttles forward and released the brakes before it was lost in the dark.
He cupped his ears and listened to the engine's pitch diminish in the distance. The uneven sound was faint. No one but a master flight mechanic or an aircraft engineer could have caught it, and Morrison had served in both capacities during his early Army Air Corps career.
An engine was slightly out of tune. One or more of its eighteen cylinders was not firing continuously.
Fearfully, Morrison listened for some sign the bomber was not going to lift off. If Dennings' Demons crashed on takeoff, every living thing on the island would be incinerated within seconds.
Then the radar man shouted through the open door, "They're airborne!"
Morrison exhaled a tense sigh. Only then did he turn his back on the miserable weather and walk inside.
There was nothing to do now but send a message to General Groves in Washington informing him that Mother's Breath was on her way to Japan. Then wait and hope.
But down deep the general was troubled. He knew Dennings. The man was too stubborn to turn back with a bad engine. Dennings would get the Demons to Osaka if he had to carry the plane on his back.
"God help them," Morrison muttered under his breath. He knew with dread finality his part of the immense operation didn't stand a prayer.
"Gear up," ordered Dennings.
"Am I ever glad to hear those words," grunted Stromp as he moved the lever. The gear motors whined and the three sets of wheels rose into their wells under the nose and wings. "Gear up and locked."
As the airspeed increased, Dennings dropped the throttle settings to save on fuel. He waited before beginning a slow and gentle climb for altitude until the airspeed touched 200 knots. Unseen off the starboard wing, the Aleutian Island chain slowly curled northeast. They would not sight land again for 2,500 miles.
"How's that number-four engine?" he asked Mosely.
"Pulling her share, but she's running a tad hot."
"Soon as we hit five thousand feet, I'll drop her back a few rpm's."
"Wouldn't hurt, Major," Mosely replied.
Arnold gave Dennings the course heading they would maintain for the next ten and a half hours. At 4,900 feet Dennings turned control over to Stromp. He relaxed and stared into the black sky. No stars were in sight. The plane was feeling the turbulence as Stromp threaded it through the ominous mass of thunderclouds.
