About that non alloyed Tie-Tanium... I still think its a very intriguing clue and potentially a powerful one since very few suspects will have been exposed to it.
Turns out non alloyed titanium has been used in aircraft manufacturing for a long time. The Douglas DC-7, a 1950s 4 engine propliner, used non alloyed titanium for its engine firewalls resulting in a substantial weight savings. Souce: Douglas DC 6 and DC 7, book by Harry Gann.
I don't post a lot but it doesn't mean I'm dormant. I have read a lot about rubber band degradation, fresh water boring insects, uses of non alloyed titanium, dredges, MAC SOG parachute ops, smoke jumpers, 727 airdrop mods and ops etc. And I spend a lot of time looking at my Cooper twenty trying to figure out how the hell it ended up at Tena Bar. \
Will be dusting off the winter cobwebs and getting back to jumping again in May. I formerly jumped year round, even jumped though hail once shredding my face in the process. Then one day, as maturity set in, I asked myself: "is it really fun freezing up here in an unheated plane with an open door, waiting to jump into a muddy windy DZ?" The answer had been yes for many years but as I cruised into my 50's I changed my view. Now I am a fair weather moderate winds wuss. I think my moderate approach has helped me avoid getting up close and personal with titanium, the kind they use for orthopedic surgery implants.
