Aw, look, it's really not hard to do research. Launch an aeroplane, let it fly around for a couple of hours, then when it gets down, take the engine apart. It's not like the airlines, pilots or engineers have much else to do with their time at the moment.
Better still, launch five, into areas with forecast different concentrations. Keep then within a safe distance of airfields. Stick a couple of observers on each to additionally report anything odd, provide additional support in case anything does go wrong. There are about a thousand aircraft sitting around doing nothing, at a guess, and the airlines are collectively losing hundreds of millions of pounds a day. There is no shortage of pilots who would be more than happy to fly a "weathership". If the crew are really freaked by something, head for home as soon as anything deviates from normal - in the knowledge that you have the undivided attention of ATC, fire services, airports .....
