How thoroughly is the flame trench cleaned, post-flight? I was wondering how much SRB exhaust residue was blown out by the Falcon-9 test fire!

Besides, anything loose would be considered FOD, and cleaned up as part of the pad activation.

However, if the question is about washing down the flame trench after each Shuttle launch, the highly corrosive elements of the SRB exhaust was washed down/away from the entire pad after each Shuttle launch as part of an effort to keep the pad from corroding. But the trench wasn't given a scrubbing per se.And the brick was largely replaced in large sections at 39A after STS-124 blew a lot of the bricks off and out of the trench at SRB ignition.Reference: https://www.nasaspaceflight.com/2008/07/investigation-confirms-vertical-debris-events-during-sts-124-launch/(Edited to include reference link)
And for accredited media peeps - do you know yet where you will be able to set up your unattended cameras for the launch yet? Interested to hear what fields of view will be available to you.
Unfortunately, no. We haven't even gotten our schedule yet from KSC.At SLC-40 SpaceX keeps us outside the perimeter fence on the East side. I would hope they don't repeat that policy at 39A, as it would put us about 1/3 of a mile away and possibly leave us with an obstructed view (Depending on how the TEL and various utility poles line up).
SFN reported in their article 1.7 million pounds. If correct that is ~188klbs for the M1DFT+ engines. That would be the fuller thrust versions.The question is the reported value correct?articlehttp://spaceflightnow.com/2017/02/12/fire-returns-to-flame-trench-at-apollo-era-launch-pad-in-florida/

Cabana: Dragon delivered to pad 39A for integration with Falcon 9 rocket. Pending normal ops and FAA license, launch Saturday a.m.
F9-032 CRS-10 Launch Hazard Areas Map (Local Notice To Mariners) for February 18th, alternatively 19th.

Maybe for if there's an engine failure and the booster burns to depletion to make up for it and then falls into the ocean?

Obviously the press site will be used to coordinate various pre- and post-launch events, but launch/landing viewing is still TBD.
(snip)Launch viewing opportunities include the usual sites: 39A press site, NASA Causeway, and the VAB roof.
Friday, Feb. 17 (L-1 Day): Kennedy Director Robert Cabana will take news media on a three-part tour of facilities in the Launch Complex 39 area. Media will depart the Press Site by bus at 8 a.m. and will receive an update from NASA on transition of government facilities to the aerospace industry, and how that approach enables NASA and industry success. Media will then depart for the Vehicle Assembly Building, where they will hear about the extensive work completed in the facility to prepare for the Space Launch System, and how that work enables members of the aerospace industry to use the facility between NASA missions. The last stop will be in Boeing’s Commercial Crew and Cargo Processing Facility, previously a shuttle processing facility, where the company is manufacturing its Starliner spacecraft for flight tests and ultimately crew rotation missions with NASA’s Commercial Crew Program.

LAUNCH VIEWINGSaturday, Feb. 18 (L-0 Day): News media wanting to view the launch from the NASA Causeway will depart the Press Site by bus at 8:30 a.m.A sign-up sheet will be available in the newsroom for media desiring to photograph the launch from the roof of the Vehicle Assembly Building (VAB). Space is limited for this activity, so media must sign up in person. At 8:45 a.m. Saturday, Feb. 18, media selected will depart the Press Site for the VAB.
