An Aeroflot Tupolev 154M jetliner crashed near Velichovsky, Czech Republic, resulting in the loss of six crew members. The aircraft departed Basel/Mulhouse Airport (BSL) with a cabin loaded with lightweight boxes, primarily tobacco products. An in-flight fire ignited in the rear of the cabin due to a malfunctioning heater in the galley, leading to a rapid spread of smoke and hindering control. The crew failed to switch on cockpit communications, impacting their ability to manage the situation. The plane initiated an emergency descent and landed in a marshy field at a high speed, resulting in a breakup of the flight deck.An Aeroflot Tupolev 154M jetliner crashed near Velichovsky, Czech Republic, resulting in the loss of six crew members.
