Let's first jump back to my original subject on the specifics of the
accident:

----------------------------------------------------------------------------
------
You stated: "The accident was caused by both pilots not seeing and
avoiding."

However, the article states: "Student pilot Sharon Hock...was not mentioned
as a factor in the Feb. 8, 2000, accident."

Further: "The probable cause of the accident was Collins' "failure to
maintain clearance from the other airplane," said the NTSB report, which is
in line with a previous federal report outlining the facts of the accident."

Additionally: ""Factors relating to the accident were the pilot's Collins']
poor visual lookout, and the . . . local controller's failure to provide
effective sequencing,"

And: "Fowler (controller) said he told Hock to turn "based on his estimate
of the elapsed time before losing sight of [her plane], and the pilot's
Collins) verbal report that he had crossed the shoreline.""

You stated: "It is a class D airport. Controllers are not responsible for
separation or sequencing at class D airports. A fact seemingly lost to many
pilots."

However, both the NTSB and the controller indicated that "separation and
sequencing" were part of the controller's responsibilities at Waukegan.

Further: AIM 4-3-2 indicates that the tower at Class D airports will provide
traffic control in the Class D airspace.
-------------------------------------------------------------

As I noted at that time: "both the NTSB and the controller indicated that
"separation and sequencing" were part of the controller's responsibilities
at Waukegan".

Do you have some information indicating that this is not correct?

You stated: 'When not specifically provided. ATC is a set of services.
Not all are provided to all people at all times."

Also, note that AIM 4-3-2 refers to "traffic control", Not ATC. I would
assume these references were to two entirely different things?

As separation is a function of traffic control, when would traffic
control
not include separation?

When not specifically provided. ATC is a set of services. Not all are
provided
to all people at all times.

IFR aircraft are separated from other IFR in controlled airspace.
Everybody gets seperated in class A and B.
VFR's get seperated in class C (and in the adjacent airspace) when in
radio and radar contact.

Otherwise there is no separation service provided.

How is a tower going to provide separation to a bunch of VFR's that are
buzzing around
with the sole requirement that they were talking to him?

Who would be responsible for separation and sequencing under these
circumstances?

You knew the answer to that. The responsibility falls on the pilot in
command.
