Jeju Air 737 crash South Korea

[Zaphod58]

I first offer condolences for all those people who are affected personally from this tragic event.

The "gears up" landing sounds to be one of multiple failures.  

I don't want to sound silly, but this is another Boeing incident to add to an already long list... I never imagined it continue to get worse.

I know it's probably too early to make guesses about this... but that was quite a fireball when it hit the fence... would that be because they still had fuel in the wings?

It's a 15.4 year old aircraft. Just because it's a Boeing doesn't mean this has anything to do with them.  Early reports are possible bird strike.

They land with a fair amount of fuel remaining usually, in case they have to go around multiple times, or divert to another airport.  The aircraft broke apart when they hit the berm, leading to the explosion.
