We were having some problems keeping Nick's dragster in the track, beacuse the launch was so violent.
We had to add two long extension reels to the power lead for that lane, to reduce the power.
We thought that had fixed it, but didn't notice that there was a bit of wood sticking out from the side rail into the lane from where the circular saw blades had dug into the rail on a previous run. The wheels caught the piece of wood and launched the dragster out of the lane.
