  this is possible due to newtons third law. for every action there is reaction in opposite direction. we need to eject a force from a heavy body downwards and an equal and opposite force upwards will result that lifts the object. engines burn fuel and release exhaust in the opposite direction giving an uplift in the other direction.

  Dear Ngrj
  I will take the example of a plane; for an object object to fly, it must have first a forward propulsion (thats why birds run fast, same as planes) before rising), with the run, a stream of air is created under the “heavy thing”, and the bernoulli effect which maintains a stream of air above and below, thus lifting the heavy object
