Time to use titanium Elon, page-3

I think Elon Musk knows a lot about Titanium (Ti). The huge grid fins are made of this material on his rockets to enable them to land back on earth. The trouble with Ti is at high temperature it burns spectacularly like a firework. The last explosion was due to liquid methane quick uncoupling which failed. Apparently liquid methane sprayed like from a wild loose fire-hose just after testing the raptor engine. My suggestion is SpaceX get better couplings and Titanium would be strong and lightweight. The huge rockets would be too expensive made from Ti but lots of engine components and fuel couplings should be made of this and maybe the recoverable space capsule if NASA will allow reuse.
