I spent a career flying a FBW airplane and I'll take the advantages of FBW over the disadvantages any day. Yes - a well designed system will have some type of back-up and I'm sure that the designers will figure this glitch out too. You are still propelling yourself into an area that we (as people) weren't suppose to be (naturally at least ), so there is going to be some inherent risk.
In my opinion it is foolhardy to think that a man-made system is going to be foolproof. I mean come on - - even the Vipers in Battlestar Gallatica and the X-Wing fighters of Star Wars fame had mechanical glitches!

I'd jump on a 7X tomorrow and have a go at it if someone (ANYONE) let me
