A Cubana Flight 389, a Tupolev Tu-154M, experienced a significant incident during its departure from Guayaquil, resulting in a collision with a soccer field. The initial engine start triggered a pneumatic valve blockage, which was rectified, and two engines were successfully started with ground power. However, the aircraft subsequently failed to rotate, requiring a 10-second abort and subsequent application of brakes. The crew, due to a prolonged checklist delay and a significant time elapsed between the start-up and takeoff, failed to properly execute taxiing procedures, leading to the overshot landing and impact with a soccer field.A Cubana Flight 389, a Tupolev Tu-154M, experienced a significant incident during its departure from Guayaquil, resulting in a collision with a soccer field.
