Third drone found in suspected Leipzig hybrid attack

According to German media, investigators have found a third drone carrying explosives near Leipzig's international airport earlier this month.
On the night of August 4, a drone carrying explosives was found near a Ukrainian cargo aircraft, prompting the airport's closure for several hours. A second drone collided with a plane that same night, while the third was discovered near the airfield 10 days later.
The airport in Leipzig is a hub for transporting military goods and serves as a base for Ukraine's Antonov Airlines.
What does the apparent coordination of these incidents suggest about the sophistication of the operation, and what options does Germany have if investigators conclude a foreign state or state-backed actor was involved?
DW put these and other questions to Olaf Böhnke, Germany Director at Rasmussen Global, the geopolitical advisory firm founded by former NATO Secretary General Anders Fogh Rasmussen.
