river testers

I dreamt that I was in front of a house. It was the house I grew up in, but not in the dream. There were jets flying over very fast. I thought it was odd. It wasn't the air show practice was it? I didn't think so. They were a different kind of jet, and they seemed to be flying with a purpose. They flew south of the house and then turned and flew back north of the house. They flew so low that the brushed the tops of trees. I was worried that they would catch on fire. Then they flew above the house and were hovering in the hair nose down. It felt a little threatening like they were in our business. There was also a woman that seemed to be wearing a contraption that made her fly. She had to have her arms and legs out, but she had a footing and places to put her hands. The contraption was a circle with her in the middle... kind of like da Vinci's drawing, but the harness, uniform etc. was black. Her son got out of the jet and started checking my house. He had a baseball cap on that said something about fish and rivers. They were testing places for drainage I think.
