I'll make landings like that from time to time when alone, but I'll
never carry passengers into a situation where there is no margin for error.


Which is scary, considering in this accident the only fatality
wasn't even in the plane.

Yes, they were truly fortunate that this wasn't much worse. Had they
hit a large truck, or something more solid, the damage to the airplane,
crew and pax could have been substantial. Fortunately, that didn't happen.

There are oil and gasoline terminals in the area of Central Ave. &
I-55, so
it could have been one large fire-ball. And news reports of the SWA
pilot
debriefing mentioned issues with the Captain have problems engaging the

thrust reversers, the co-pilot had to "force" them.

I-55 is a LONG way from the departure end of 31C -- a little over a
mile. Remember, this was a landing accident, and they didn't even make
it across S. Central Ave.

That happens when the struts aren't compressed and/or you have no wheel
spin-up.

That night at MDW was the place for a crew who had cut their aviation
teeth on Great Lakes winter ops. The name "SOUTH WEST" doesn't paint
that kind of a picture for me.

"Chicago Tribune: Midway radios crackled warnings"

The Chicago Tribune is reporting today that controllers and pilots
were concerned about the choice of runway 31C and the unavailability
of runway 13C, which would have been preferable given the wind.

[....]

I'm amazed that the Chicago Tribune authors would suggest that 13C
would be more preferable because it slopes upward by 5 feet from one
end to the other. I think it's a very minor benefit. That kind of
detail, while ignoring the actual length of the runway is curious to
me.


The five foot difference in elevation would not bother me much. The
tailwind incurred by operating on 31C rather than turning it into a
headwind on 13C, given all the other circumstances, would bother me a lot.

There comes a time when somebody in the airplane has to make a decision
unencumbered by concerns for schedule, cost, or convenience. When you
do, you can never know whether doing so made a difference, but you will
always know it was the right thing to do. Every Thanksgiving (and the
other 364 &1/4 days of the year) I give thanks that almost all of our
decisions are correct. But when we have to wait to know that until after
the fact, it's the same as rolling the dice.

But tanker trucks in the intersection were a possibility, 55th st. is a
good alternative
when I-55 is gridlocked.

They serve SLC, DTW, BUF, RNO and many cities in the Northeast, so
snow is nothing new. And the crew was based in BWI, plenty of snow and
freezing rain.

Aren't 31C and 13C physically the same? Just landing into the southeast
on 13C
as opposed to landing on 31C, into the northwest and with a tail wind.

I assume you are asking how much of a difference there is between nine
knots of tailwind and nine knots of headwind.

A great deal, especially when all other factors are at best marginal.

Yes, it's the same pavement. The Tribune points out that using 13C would have
given the pilots a headwind instead of a tailwind. Someone earlier said there
was a 7 knot tailwind? In that case, using 13C would have meant that the plane
would have been traveling over 16 statute miles per hour slower when it touched
down. Due to the differences in displaced thresholds, runway 13C is also 223'
longer than 31C.

IOW, if runway 13C had been in use, there would have been no overrun and no
accident.

Possible conflicts with O'Hare (and the possible resultant holds...)
wouldn't have any bearing on a decision by Midway to turn or not turn the
airport around...would they?

Just wondering out loud...
