In March 2018 David Olshefski and I went to explore the last bastion of old lane-houses in Shanghai that are soon to be torn down, Laoximen. The purpose was to provide That’s Shanghai with aerial photos of the area to get a unique perspective of the scale and layout of the old city in Huangpu District. The photos were then incorporated in the article written by Dominic Ngai. One photo shows the result of a mishap flying the Phantom 4 when a gust of wind blew the drone into a sign on a nearby building. Oops!
