Plane door opens mid-air.

The shocking incident happened in 

Brazil while the plane was carrying 

20 passengers. From the very start

a strange sound was heard by the

passengers . Even the regulars who

frequently travelled by air- became

suspicious . Then suddenly with a bang 

one of the doors opened and

a gush of wind overwhelmed the

boarders .They became alert and

immediately reacted by holding the

door as fast as they could. They heard

 the propeller hitting the door repeatedly. 

The Pilot however kept his calm and

landed the plane  safely.
