SpaceX has been working on the catch arms on tower A. They did some test 'catches' and have been busy making modifications based on the results. All the man lifts have been removed so it looks like they are done.
I just saw a report that the FAA is holding up next flight approval due to environmental concerns. It seems some environmental groups are complaining about the 'waste' water being used in the deluge system and it's effects on the environment. FAA sent note to SpaceX that it probably would not approve next flight until sometime in November!!???
No wonder Elon is complaining about regulations/red tape.
