The IAC and the entire aerobatics community is saddened at the news of Warren Cilliers having passed away on November, 8th, 2025 after an aerobatics accident at the Keystone Heights Airport in Starke, Florida. 

Warren was an exceptional aerobatic pilot, a talented mechanic, and great friend to many in the aerobatics and aviation community.  Warren was an active IAC member and left a lasting impact on many aspiring aerobatics pilots across all experience levels. 

Our thoughts and prayers are with Warren's family and loved ones.
