Max- Squishy Balloon

  I sped up, leaving the plane behind, and concentrated on the ground, scanning the area a good distance out. I saw no vehicles, no—

  I don’t know what made me look up at that moment, but I did, and suddenly, not fifty feet in front of my face, was a huge, clear—jellyfish? I was going almost three hundred miles an hour, and I plowed right into that sucker.
...

  IT WAS LIKE hitting a squishy balloon. Going as fast as I was, I sank deep into it, as if I’d hit a bouncy castle face-first and vertically. My head was pressed against a thick, smooth film, and for several horrible moments I had the feeling of being smothered, my wings bent painfully back. Then, boing! I bounced out of it, arms and legs flailing wildly, my stalled wings causing me to drop quickly before I could catch myself.

  What the heck?!

  It had literally bounced me back about sixty feet, and from this distance I could see that it was a huge, clear, weird thing. It was practically invisible, and I realized with shock that there were hundreds of these balloon-type things, each one as big as a city bus. They were all tethered to the ground below by hairlike, glistening metal wires.
