They all said something about TPS "tiles"??
We would want to see the transcript of what Musk actually said. The Twitter feed I was following said "300 or more."https://twitter.com/EmreKelly/status/994648133840920578
Take 100 flights with a grain of salt. If each F9 B5 could fly up to 10 times it would be already a great achievement. Currently the most a F9 core has flown is two times with 4-5 months needed for refurbishment. Also, some parts may be certified to fly 100 times, but if you change 99% of the booster, is it really the same one?

But we all know the world hanged rapidly, paradigms are shifting and BFR is looming...Meanwhile competition with old-space seems way behind them... How long ago did Russia joke about using a trampoline? Some customers are specifying brand new boosters, and I'm sure some FH center cores will go into the drink. it's not inconceivable that these two numbers add up to twenty-something boosters over the next 5 or so years.BFR will probably be here before any boosters hit the century mark.

Elon said "up to 300 missions" for F9 B5.

I'm sure as soon as someone posts a recording of the call, theinternetFTW will end up posting a transcript to his github.
Active water cooling of the base heat shield during reentry?!

40% margin is not a requirement

F9 can take a single engine out at any time in the mission and still complete the mission. Atlas and SLS have fewer engines to offset a single-engine failure, so I would love to know how they pass the NASA human certification.
