May aerobatics be performed over a controlled airport without getting a waiver? CFR 14 Part 91.303 states:

Aerobatic flight.
No person may operate an aircraft in aerobatic flight--
(a) Over any congested area of a city, town, or settlement;
(b) Over an open air assembly of persons;
(c) Within the lateral boundaries of the surface areas of Class B, Class C, Class D, or Class E airspace designated for an airport;
(d) Within 4 nautical miles of the center line of any Federal airway;
(e) Below an altitude of 1,500 feet above the surface; or.
(f) When flight visibility is less than 3 statute miles.
For the purposes of this section, aerobatic flight means an intentional maneuver involving an abrupt change in an aircraft's attitude, an abnormal attitude, or abnormal acceleration, not necessary for normal flight.

For the purposes of this question I want to focus on paragraph (c). Assuming we don't have any other specific permission (waiver), may aerobatics be performed above class B, C, D, or E surface airspace?
I know aerobatics may be performed under the outer rings of class B and C airspace.
There also doesn't appear to be anything preventing aerobatics above the outer rings of class B or C airspace.
So the question is focusing on the center core (the surface area) of class B and C as well as the typical cylinder of a class D airspace and whatever shape a class E surface area happens to be.
Paragraph (c) simply states &quot;Within the lateral boundaries of the surface areas&quot; but makes no mention of altitude (other than the 1500' AGL reference in paragraph (e)).
Obviously we are talking about surface areas that go to the ground so clearly you may not fly in or below these surface areas. But may you fly above them as long as you are 1500' AGL?
&quot;within the lateral boundaries of&quot; has no implied altitude restriction. That term, in English, implies surface to outer space. So it would seem that aerobatics may not be performed above a class B, C, D, or E surface area at any altitude.
But you may perform aerobatics above the outer rings of class B and C. So why restrict doing them over the surface area?
Is there an official answer? May I legally do aerobatics above class B, C, D, or E surface airspace?
I have searched and looked at many related topics but none address this specific question. Even the Hucker discussion leaves this unanswered (to me at least) which only clarifies being able to do aerobatics under (no mention of over) the outer rings of class B and C airspace.
Actually "within the lateral boundaries of the surface areas of any Class D, Class C, or Class B airpace" DOES imply that you are not permitted to do aerobatics over these areas without special permits from the FAA or if there is a designated aerobatic box at that airport and said pilot remains within that airspace.  Even if you are not in the actual airspace itself, if you're above it, you're not allowed to fly acro over it.

Now, note the term "surface areas" could imply that you could fly aerobatics above or below Class C or Class B airspace SHELVES, that is a section of Class C or Class B airspace which does not touch the ground,  provided you don't enter those areas and and said airspace meets all the other requirements of FAR 91.303.

Also, some elements of the question may be interpreted in a way that would lose sight of the distinction between Class-E-to-surface areas "designated for an airport"-- i.e. actually surrounding the airport whose approaches they protect -- versus Class-E-to-surface "extensions".   Or perhaps the questioner was fully cognizant of, and following the example of, the language used in the AIM, as well as in the section headings of FAA Order 7400.11B, "Airspace Designations And Reporting Points".  In these places the phrase "Surface Area" is used ONLY to refer to Class-E-to-surface areas that surrounding the airports whose approaches they protect, and not to refer to Class-E-to-surface "extensions".  At any rate, the Class-E-to-surface "extensions" do not fall within the meaning of "Within the lateral boundaries of the surface areas of... Class E airspace designated for an airport".  One clear way to refer only to those Class-E-to-surface airspaces that actually surround the airport whose approaches they protect, is to include the phrase "designated for an airport".  For much more on the meaning of "Within the lateral boundaries of the surface area of... Class E airspace designated for an airport", please see this answer to the question "Which parts of class E airspace can an ultralight (part 103) fly in without prior ATC authorization?", as well as this answer to the question "Does FAR 91.155c apply to class E surface extensions?"
