A netizen recently experienced thick fog filling the aircraft cabin after boarding, causing panic as visibility became extremely poor. Many passengers and even flight attendants explained that this phenomenon is called 'condensation' when cold air encounters hot air inside the plane during air conditioning, causing a cloud of mist. Despite the initial scare, everything returned to normal once the plane took off, with many netizens reassuring the original poster that this is a common occurrence.
