We've had a lot of questions about how they behave compared to traditional helicopters or airplanes. We were not unique, and a lot of other countries had similar questions, like developing modelling like Accolade. If you spread that quantity at that speed, where would the droplets fall? That's why we work internationally, through EDC and with industry, to develop models, for example.
There were also questions...because an airplane might be filled once or twice, whereas a drone is typically smaller and will have smaller reservoirs, so how often do you need to fill it? That is part of the risk assessment. If you fill it once, you're exposed once. If you fill it 20 times, you're exposed 20 times. Those are some of the questions we're trying to address to make sure that they can be used safely. We do believe that the technology will help, and we're pushing everybody to move this as quickly as we can.
