I am 88 yrs old now, but when I was 50 (about?) my husband flew us in our Bonanza to Jungle Rudy’s where we landed in the fields and stayed with him for a few days.
He showed us his maps so we could try to fly into the canyon by Angel Falls. It was plenty tricky because you had to go when you could see, but the sun made mist form and socked the canyon in soon after dawn.
People had tried it before us, but didn’t make it. We did, and it was one of the biggest thrills of my life. I have pictures I took as we flew right past the middle of the falls. Dangerous, but worth it. Rudy said we were only the 5th plane to go in there. One or two had crashed as I recalled.
We went back to Rudy’s 10 yrs later, but didn’t go into the canyon again. My husband is gone now. He was a wonderful pilot and we made many more such exploits.
