Serious problem of Ukrainian airmen. Long war has an impact

The case was reported by a pro-Ukrainian account on Telegram, which is cited by the Ukrainian defence Blog portal. It is primarily about working on kind fighters[ MiG-29](https://defence24.pl/technology/unknown-serbian-mig-29-with-Chinese-missiles), Su-27 and L-39 Albatros school-fighting aircraft (so it is not said about Su-25 combat field aircraft or the fewer Su-24 front bombers). Paradoxically, it is not about aircraft that have been utilized in combat and training (Albatros) for 4 years, and are exposed to overload. The problem is individual equipment, including life support systems.
