That article really emphasizes the complex nature of the Transporter/Erector/Launcher (TEL) system and just how critical it is for a successful liftoff of Falcon Heavy. Once it clears the tower everyone will be able to breathe again. Interesting, the first FH payload still remains a mystery.
I think it is a test payload, not very interesting. If there is a paying customer on it, they don't mind losing their payload!
