Default Should SpaceX use larger but fewer engines for reliability on the Falcon 9?

I find it mildly amusing that you think a "large fireball" is not
nearly as hazardous as an "explosion".


Because it's not as hazardous, especially when you have a launch escape
system in place to get you away from the fireball.


As a check, since I have peanut-gallery difficulty with fireball vs
explosion Was it a large fireball that enveloped (?) Challenger?



Let's put it another way. On Mythbusters when they use lots of gasoline
to create a big orange fireball, that's NOT an explosion. When they use
a high energy explosive, there is usually very little in the way of a
"fireball", but there is *always* a well defined pressure wave that
shows up in the high speed video. That pressure wave is the telltale
sign that you've got a true explosion, not a fireball.


For those who haven't seen it:

Watch:

You'll see the pressure wave move across the desert. Quite impressive and
scary.

(And on-topic for Challenger actually).

Good Lord, Bobbert FINALLY got something right!


....When did you kids stop calling him "Bbo Hallr"?

Even a stopped clock is correct twice each day. ;-)


....And in this case, the clock is clearly of the cuckoo variety. Hopefully a sterile one as well.
