Would UAV be any good to check the "intensity " of the cloud
Why would anyone have a UAV already kitted out with the necessary instrumentation?
(You could gaffer-tape a sticky lampshade to the fuselage, examine it on landing and say "yep, there's sharp glass bits somewhere up there". But designing and building instruments that can tell you anything quantitative is going to take, er, a few days.)
... or the consequences?
It's
your turn to look up the turbine blade temperatures on a range of jet-propelled UAVs and compare them with those for a range of commercial aviation donks...
