I guess the last time was in 2013. Asiana Airlines Flight 214, a Boeing 777 jumbo jet, crashed at SFO with only 3 fatalities. Those are tough airplanes and low-speed crashes are often survivable if passengers can evacuate before the inevitable fire spreads.
I was going to say that the 777 isn't a jumbo, but it looks like they're now calling it a 'mini jumbo'. Feelings of inadequacy, I guess, compared to the 747.

It was kind of freaky seeing the burned-out wreck sitting next to the runway when I flew out of SFO a few days later.
