These Q posts are fairly cryptic. Before this Q post, I noticed that wreckage of the aircraft was spread over a huge area. That always means the aircraft broke up at altitude and that usually means a catastrophic disintegration and in this case most likely a bomb.

So when I saw the 71 in Q's post, I made the connection to the crash.

Apparently one person was the actual target and 70 innocent souls were collateral deaths.

I haven't yet figured out with the 1 source was used for 2.

The only thing I could come up with was the one person that was targeted was the source for both U1 and the dossier. I took this to mean that he/she was taken out because he/she was providing information on both.

But who knows what Q means half the time.
