Indeed rockets landing on people do happen, happened too me, though at the stage the fall most of the time (like nearly all) have already burned out and just a stick that hits you on the shoulder and you think a bird has shat upon you it is just so low impact. Least the one that bounced of me. But your spot on the odd's are low and even then the chances of it causing damage are low. It is the ones that go off incorrectly at angles into the crowd that people worry about and with that one bad rocket at a public display - it happens. Still if these seeds when deployed clump up, gain moisture and freeze together into a large ball of ice and seeds - then it could be most epic a landing.
