Anyone have a good older dig on this? I could be mixing this up with another missing plane, but here we go.
Malaysia Airlines Flight 370
Wasn’t this the one where we lost a bunch doctors or scientists curing [cancer or something really important]?
Trying to search today leaves me confused with losing a bunch of calligraphy artists and the impression that I am supposed to swallow some made up bullshit 🧐

As stated, I could also be thinking of another flight. I am specifically looking for some event including the loss of a significant team of scientists or doctors where a plane was never found. Please and thank you for helping me fill in the blanks.

Edit/update:
I appreciate the responses so far!
I think maybe it was AIDS researchers, so MH17 is maybe where my head was going on this:
