Ukraine has suffered the loss of its first F-16 fighter jet during combat operations against Russian forces, leading to the death of pilot Oleksii Mes. The crash occurred on August 26 while the jet was involved in a major Russian missile offensive, but preliminary investigations suggest it was not shot down by enemy fire, with potential causes including pilot error or mechanical failure being explored. Despite this tragic loss, the F-16s had demonstrated effectiveness by intercepting four Russian cruise missiles during the engagement. The incident has sparked speculation, with pro-Kremlin sources claiming the aircraft was destroyed on the ground during a missile attack, though this remains unconfirmed. The crash and the loss of such a critical asset mark a significant setback for Ukraine as it continues to strengthen its air defense capabilities amid ongoing conflict. A special commission has been dispatched to investigate the circumstances surrounding the incident.
