Let Serve
A serve that touches the top of the net and still crosses into the other court. The ball is live. Play it. The net can knock the serve off its path, which is why a let serve is awkward to pass. If the ball hits the net and does not cross, or it hits the antenna, it is a service error. Let serves are legal under current FIVB, NCAA, and US high school rules.
Example
A float serve clips the tape and drops short, in front of the passers who had backed up for a deep ball. It lands in. The rally is live, and if nobody plays it, the serve is an ace.
