Been a while since I last posted here, but here's some random ideas I have for aircraft belonging to the KLE Weather Corps.

"Thunderstorm" could be an aircraft, either an airship or plane, that is able to electrocute aircraft and fry their electronics, possibly by manipulating electrons within cloud formations and striking them with lightning bolts.

"Hurricane" could be an airship with the ability to manipulate the airflow. In real life, hurricane winds can cause turbulence if a plane is flying too low, so its operational altitude might be rather limited.
