Check out Alex' footage of an entire canopy being sucked into the burble at pull time.
Main canopy sucked into burble of wingsuit from Alx72 on Vimeo.
Jump with very large wingsuit and small high performance canopy (non crossbraced) with short line trim.
Pilot chute pulls canopy out of the bag, pilot chute collapses.
Canopy then gets sucked into the burble of the wingsuit and does not catch air, bounces around on the back of the pilot. Pilot makes body movements, canopy catches air and inflates properly. Landing without any issues. Pilot is a very experienced skydiver, wingsuit flier and base jumper.
Many questions come to mind when watching this.
- How well does a main canopy open after dancing around inside a burble for a while?
- How much does line length influence the opening?
- Could cutting away leave you with a canopy lingering inside the burble?
- How well will the reserve open, if of similar small size?
- And how much altitude will be lost in the process?
Enjoy the video, and keep it in mind when you consider your canopy choice for wingsuit jumps.
