This is incredibly important. There is no point maintaining a noble vision for peace in space whilst risking harm [or worse] to aircrew and air passengers. Thus we have standard operating procedures and a risk register in place. We only perform outdoor laser activity when the ONLY airport within 40Km is closed for business. It is worth noting that even for this closest airport, we are outside the UKs defined notification zone. If we applied rather stricter US guidelines to our practice, we would define our laser site as a “normal flight zone”. However, with our laser specifications, we would also satisfy the safety requirement for lasder use in a “sensitive zone”.  We also always employ live monitoring of aircraft via flightradar24 App. We routinely use a laser mounted to a GOTO telescope, which means it automatically follows the target planet, leaving more human focus directed at safety [night sky monitoring together with flightradar24]. If using a class 4 [powefull] laser in a large open area, we will also use a knowledgeable assistant to act as spotter [for people and planes].
