Boeing 747 making a huge comeback

Nation building via learning and being the best in business

Many slip ups and accidents with the 737 and lately the 787 have made Airbus the plane maker of choice of the world.  However the 747 is making a huge comeback for the freight and cargo side of air transport

Airliners have abandoned the 4 engine jumbo jets in favor of the two engine configuration that can carry less passenger but same range.  A two engine plane consumes 700 to 1000+ gallons per hour saving many airlines millions of dollars in fuel charges.   

Two engine has lesser effect on carbon emissions, on noise pollution And is favored in passenger air transport.  But its another story for cargo side of business.   More payload, more flexibility in cargo configuration which can translate to lower cost.   Most of the cargo carried are pharmaceuticals and electronics
