Because new things are learned.
Malta used lidar technology in 2015 and discovered a B-24 Liberator that went down on May 6th, 1943. It took several years to recover the remains of a single serviceman who didn't make it out of the aircraft.
My b-i-l wasn't yet born when his 21-year-old cousin was K i a until a DNA test confirmed a living relative could make the decision about the remains of Sergeant Irving R Newman

Just today I listened to this amazing #MLStreetTalk with @tdietterich recommending:
» I think everybody should read #NancyLeveson book
'Engineering A Safer World'
because what she says is you don't build a #SafeSystem and then deploy it.
Safety is a really a control concept that a system is...we need to be constantly controlling and modifying the system to keep it safe.
And think it's very similar to this problem of the #UnknownUnknowns «
Fediverse, your eyes, if I may.
Found this. It’s a dispenser for a kind of green wax, slightly greasier to the touch than beeswax, not so greasy as boot polish. It does not fluoresce, nor smell. It’s maybe 40 years old, and would probably have been either automotive or agricultural use but we can’t tell which. Less than 1cm of it has been used and I don’t know if anyone would want it if I knew what it was for, but I doubt I can use it.
Any thoughts?
