My friend Fred Barton posted an explanation for the "human error" that nearly killed Christopher Tierney on Monday at SPIDERMAN:
"Tierney was wearing a harness and a tether that was supposed to prevent him from free-falling, but “someone missed their cue and forgot to anchor the tether,” according to a production person who worked on Monday’s performance." (Wall Street Journal.)
In other words, the irresponsible production had no check and balance for such matters as a temporary memory lapse. When you're playing with human lives, that's really irresponsble. I hope this shuts the damend show down.
