Chapter 9
the intervening weeks, design and repair of
the faulty runway/taxiway had undergone a
handful of evolutions--as if no one was com-
pletely sure how to stabilize the earth sur-
rounding a couple of hulking pipelines and
keep the runway eight feet above from ever
sinking again.
While these same engineers were trying
to come up with a fix, Bobcat Contractors
was pumping water out of the trench, and
had been for a solid three weeks. Then one
of engineers got wind of all the water in the
trench and threw up his hands in despair. No
one had bothered to mention the water prob-
lem and the resulting foot-thick mud. If they
had he would have told them that any chance
at compacting what amounted to a few dozen
tons of sludge was not only a waste of time
but couldn't possibly support the runway and
60,000 pound jet.
In his e-mail Jim Craig had a final bit of ad-
vice. If it were up to him, he'd excavate around
the pipelines, pour in enough concrete to cov-
er the pipes (and then some), lay in some fill
dirt in lifts, tamp it, rebuild the section of run-
way/taxiway, and be done with it.
Which by mid-July was more or less what
happened.
