13. A once-in-a-lifetime jump

Eventually I got the Ohka under control, the altimeter settled down and I was able to turn my attention to the ground. But where was the field? 

After searching frantically I picked out the Toné River. I knew the field was quite a way to the left of it. But all this time I’d been flying away from it at full speed. 

Ever more difficult

I had to quickly bank left, but when I tried to do so the nose of the K-1 didn’t turn at all. Then I remembered, I wasn’t flying a Zero. The Zero would’ve banked right around with that much aileron input. Apparently the K-1 also needed some rudder to turn. 

“Come on, turn,” I yelled, pushing hard on the foot bar and deflecting the stick all the way. 

When I did so I felt tremendous wind pressure strike the right side of the K-1 as it skidded violently to the left. The wind was so strong that it pushed open the canopy and blew my face out of shape.

“Shit!” I thought, realising that I’d grossly over-controlled it. Switching the stick to my left hand I reached up and slammed the canopy shut. This only added to my workload, and all while I was steadily losing altitude. 

Establishing my approach was becoming ever more difficult.

High and fast

I finally got my bearings and was able to devote all my attention to my approach and landing. Problem was, the canopy still wasn’t completely closed. I tried jerking it back and forth but it wouldn’t budge so I gave up and turned my attention to the altimeter and airspeed indicator. 

I was already down to 1,500 meters. At 1,000 meters I’d have to deploy the flaps. 

I still had 500 meters to go but all my floundering around had cost me dearly. The ground was coming up rapidly. The No. 2 airfield was only a couple of kilometres or so in front of me, but I still had to fly the long downwind leg parallel to the runway before making the 180° turn to final.

Afraid I didn’t have sufficient altitude and that I ‘d land short, I decided to land from the opposite direction, from my present position. This meant I’d come in high and fast, but if I did everything just right I figured I’d touch down at mid-field and roll to a stop before going off the end.

I had a bigger problem

Descending rapidly I soon passed 900 meters and went to deploy the flaps. The lever wouldn’t budge, probably because I still had too much airspeed. This was a serious problem. 

I raised the nose to slow down. When the airspeed dropped I was finally able to get the flaps down.

I was now in the final stage of my flight. Judging by my speed and height I realised that had I continued with my original pattern I wouldn’t have made it. So my decision to land from the north rather than the south was correct. 

However, when I began to set up for my landing I could see that I was still too fast and too high. 

Too late to worry about it now. I had a bigger problem. I was going to land long – way long. 

Touching down midfield was impossible. Even if I did everything right I probably wouldn’t touch down until reaching the very edge of field. This meant the navy’s top-secret super-weapon would end up in the local village where everyone could see it.

I pushed the stick forward to descend faster. But that only increased my airspeed. 

Shooting along at low altitude in ground effect the K-1 refused to descend further. Attempting to force the nose lower had no effect. The K-1 remained stubbornly horizontal.

With increasing dread

The reasons for this were simple: The K-1 was small and sleek and, with no landing gear or other drag-producing protuberances, it was aerodynamically very efficient. It wanted to fly. 

It was also very heavy for its small size. The heavy ballast in the nose — installed in place of the warhead to maintain the proper weight and balance — meant that it retained a huge amount of inertia from the dive, energy that was converted into airspeed and which took time to dissipate. And at the high speed I was going the wings were producing so much lift that the craft simply refused to settle down towards the field.

By this time I was already more than two-thirds of way across the field. No matter what I tried the K-1 simply zoomed along low over the ground. 

With increasing dread I saw the border of our field rushing towards me through the windscreen. The wooden hangar at the field’s edge was coming up fast. 

Stunned into disbelief

In desperation I forced the K-1 onto the ground onto its wooden landing skid. This belly landing was akin to landing a normal aircraft gear up and letting it slide along the ground. 

There would be a tremendous impact when it contacted the ground at this speed, but I was hoping the friction would slow the K-1 enough to prevent it from hitting the hangar and crossing the airfield boundary.   

That, however, was the last of the many miscalculations I made that day.

The skid was flexible so when it hit the ground with a violent impact the K-1 bounded into the air again. This wasn’t merely ‘ballooning’. The K-1 literally jumped upwards almost 150 feet and leaped clear over the hangar! 

Stunned into disbelief, I instinctively pushed the stick forward. The K-1 scraped the hangar’s roof and, like a wild animal escaping its cage, headed for the field boundary. 

In amazement I watched the hangar pass below me. That was one obstacle out of the way. Now, ironically, I felt I needed to retain airspeed and keep it flying. But after that final spurt the K-1 was finally losing its energy. It plowed through a gravel mound just outside the field boundary, sending a shower of gravel in all directions. 

On the ground to stay

Ahead of me I could see a small cluster of barren trees and a farm field coming up fast. And I vaguely remember that between the trees was a house. 

Although my K-1 was now definitely on the ground to stay it was still carrying a fair bit of speed and I had no idea where it was headed.
