Since the dawn of commercial aviation in the 1920s, the popularity of air travel has grown at an insatiable rate. Today, more 3.5 billion passengers travel by plane each year - equivalent to half of our planet’s population. With technology, design and enhanced fuel efficiency now allowing commercial aircraft to fly faster and cheaper than at any point before, the ever-increasing demand for air travel shows little sign of relenting.
Look up into the skies today at a passing aeroplane and the view is not that much different to the one you would have seen 60 years ago. Then and now, most airliners have two wings, a cigar-shaped fuselage and a trio of vertical and horizontal stabilizers at the tail. If it isn't broke, the mantra has been, why fix it, particularly when your design needs to travel through the air at several hundred miles an hour packed with people.

Notre-Dame has occupied the heart of Paris for the better part of a millennium, its twin medieval towers rising from the small central island wedged between the storied left and right banks. Now, France is burning.
A team of Tel Aviv University researchers revealed the heart, which was made using a patient’s own cells and biological materials. A team of Israeli researchers has “printed” the world’s first 3D vascularized engineered heart. On April 15, 2019 a team of Tel Aviv University researchers revealed the heart, which was made using a patient’s own cells and biological materials. Until now, scientists have successfully printed only simple tissues without blood vessels.
