Incredibly sad.
I logged lots of happy hours in that aircraft back in the day.
I agree. A tragic event such as this is always so sad for those of us in the aviation fraternity - and of course even more so to those closer to the people directly involved.
It somehow seems to hit especially hard if you've been a pilot or even passenger in the aircraft involved. There is a kind of sad poetic nostalgia to be experienced here, and I've been affected by it a few times - once after a C-210 accident where all aboard perished; I had been in the RH seat of that aircraft only a few days before, and had hand flown most of the more simple part of the route. The others were the loss of a couple gliders in which I had logged up quite a few hours in my own solo adventures. Deepest sympathy to all involved.
