edit: In summary/TL;DR SkyPan was explicitly allowed to operate a 55lb drone commercially if they stayed at an altitude less than 400ft, the drone would fly home after a lost connection for safety, they were more than 500ft from people, and were 5 nautical miles from an airport UNLESS THEY HAD WRITTEN CONSENT from air traffic control authority.

The FAA has only issued 333a exeptions for commercial drone use to ~399 firms, one of which is SkyPan. Exemptions are case by case. They give these FAQs[1] on their site breaking down what that permit is.

Here are some excerpts from the SKYPAN exemption. These are issued as letters if you see the link[2] below and are evaluated on the case by case basis, following are relevant intersting excerpts specific to skypan[3]:

ESTABLISHED PRECEDENCE

====================================

> FAA found that the enhanced
safety achieved using an unmanned
aircraft (UA) with the specifica
tions described by the petition
er and carrying no passengers or
crew, rather than a manned aircraft of signi
ficantly greater proporti
ons, carrying crew in
addition to flammable fuel, gi
ves the FAA good cause to find th
at the UAS operation enabled
by this exemption is in the public interest.

TYPE OF VEHICLE

====================================

This is the operating drone Specs:

> Operations authorized by this grant of ex
emption are limited to the Align T Rex 700E
F3C when weighing less than 55 pounds in
cluding payload.

GENERAL RULES (speed, altitude, oversite)

====================================

> may not be operated at a speed exceeding 87 knots (100 miles per hour).

> The UA must be operated at an altitude
of no more than 400 feet above ground level

> All operations must utilize a visual observer (VO). The UA must be operated within
the visual line of sight (VLOS) of the PI
C and VO at all times. [I think PIC is person in control]

OPERATING AROUND AIRPORTS (SkyPan)

====================================

The UA may not operate within 5 nautical mile
s of an airport reference point (ARP) as
denoted in the current FAA Airport/Facil
ity Directory (AFD) or for airports not
denoted with an ARP, the center of the ai
rport symbol as denoted on the current FAA-
published aeronautical chart, unless a lett
er of agreement with that airport’s
management is obtained or
otherwise permitted by a COA issued to the exemption
holder.

OPERATIONS AROUND CITIES (SkyPan)

====================================

All Flight operations must be conducted
at least 500 feet from
all nonparticipating
persons, vessels, vehicles, and structures unless:
a.
Barriers or structures are
present that sufficiently pr
otect nonparticipating persons
from the UA and/or debris in the event of an accident. The operator must ensure
that nonparticipating persons remain under
such protection. If a situation arises
where nonparticipating persons
leave such protection and
are within 500 feet of
the UA, flight operations must cease immediately in a manner ensuring the safety
of nonparticipating persons; and
b.
The owner/controller of any
vessels, vehicles or struct
ures has granted permission
for operating closer to those objects and
the PIC has made a safety assessment of
the risk of operating closer to those
objects and determined that it does not
present an undue hazard.

[3]In the letter the decision is based on other proposals, so some of these rules are possibly boilerplate. However, as an exemption, when I say "specific", I mean these are grants, so these are rules and allocations the entity (skypan here) must follow, not neccessarily applicable to other providers.
