When we've discussed this with our stakeholder group of people in this industry, one of the challenges is that, based on our current regulatory environment, you're not allowed to actually fly the drones and spray with the drones to collect the data to prove that it's safe. You have a chicken-and-egg problem.
The regulatory sandbox.... If the concern of the PMRA is that you don't want people having carte blanche to go and spray unapproved chemicals in unapproved ways, then create a limited environment where you can collect the data and prove its efficacy. It could be one acre or 10 acres; it doesn't need to be big. You have a statistically insignificant amount of impact that it can generate, but you can collect the data that you need to prove the safety.
