Thank goodness nobody was hurt in the stampede!

Anyway, a couple educated guesses:

- fleet management and compliance

- authN / authZ, both by operators and determining allowed functionality of the drone itself, for the BigCos with multi-use drones used across depts

- simulation, QA

- modular equipment

- repair services hardware + software (unless economy of scale renders replacement a better deal)

Drop me a line if you're thinking about any of this.
