I wonder when organizations and companies will realize that it is not wise for everyone to take the same plane. 100 of the world's foremost HIV scientists died on MH17... A tragedy that will have enormous consequences for untold thousands of people...
This is why my immediate family will never be on the same flight all at once. We may not be super important in the grand scheme of the planet (ie curing cancer scientist family or anything), but my old man always said it was silly because what happens if the flight goes down, then we're all gone at once.
For family vacations we usually split between 2 and sometimes even 3 different flights.
I believe the saying goes, "Never put all your eggs in one basket..."
... my sympathies to those affected by this horrible event.
