Because it isn't easy to have a constant stream of planes flying into a hurricane. Limited resources = this. Things need to be done by a standardized schedule as well.Why are they obsessed with having no recon for like 6 hours then 3 hours of simultaneous recon
There's literally nothing wrong with doing it this way, we can extrapolate intensities without risking the lives of people too. Although each individual plane pass is technically a minimal risk to the lives on board, it's still a risk nonetheless.
