Wind bag

It’s the largest vertical wind tunnel in the world apparently.  Ex-MoD.  I’m not that experienced but after watching the formations flying before us, I thought: that looks easy.  Session 1.  Slightly timidly launched myself into the air stream only to sink straight to the floor.  “De-arch to rise,” he’d said.  90 seconds of wrestling later I’d enjoyed a few fractions of a second off the bottom grill.  Session 2.  Every time I followed the Instructor’s directions I’d sink.  I’d de-arch and tumble around like a leaf for a moment.  Not happy. Two thirds gone - no flight whatsoever.  Session 3.  Exactly the damn same. Furious.  Only in the debrief I am told that he’s trying to keep me on the floor.  If I’d wanted to lay on the floor I could have stayed in my lounge and not travelled half way across the country and pissed £30 away in five minutes.
