CSTG member Perse has been abusing a basic exploit with the glider, on a nightly basis, to fly across multiple zones and barrel bomb / oil jar boats and tames.
You can literally watch him doing it on stream right now.
All you need to do is fly upwards and drag the glider to a new slot on your bar to avoid the CD and reopen the glider, gaining altitude.
