The issue with the safety fence at Oxford for that last Flat Track meeting was that the safety fence on the bends was altered at the end of the 2003 season to accommodate the new air fences, which were made compulsory at Elite League tracks in 2004.In order to maintain the width of the track, the original fence was removed and a new structure was fitted 50cm or so further back, just using solid scaffolding poles as posts with a weld mesh to mount the air fence to, therefore making the new fence unsafe without an air fence in front of it.
This was the concern with using the track without an air fence
