> Aeroplane wings take the air coming towards them (caused by the existing velocity of the aeroplane) and direct it down and backwards; this creates a resultant force that is forward and upwards. Well wings typically don't provide thrust but drag, i.e., a resultant force that is backwards and upwards. So according to Newton they would be pushing air down and forwards. The engines overcome drag and give a net forward force.
