Welcome to the Summer 2016 issue of Airside International, where we cover the challenges facing airports as they seek to grow their infrastructure sufficiently quickly to meet the fast-growing demand for flight operations that so many of them face; the potential for new forms of aviation fuel that so many airlines and other interested in parties are researching and assessing; GSE maintenance, and how equipment operators are ensuring their GSE works whenever they need it; and, finally, we look at the twin threats posed by drones flown in close proximity to airports and lasers being stupidly and criminally aimed at aircraft landing or taking off.
