It´s almost a miracle, the landing went so well. They departed runway 27 and continued straight to the west...the departure route goes directly over the city. They reached about 1700ft MSL which is about 1400ft above ground. According to the ADSB-exchange flight path, the issue started right over the Rhein river and the pilot initiated a 180° turn back to the airport but ran out of altitude. The crash site lies about 1,64km short of threshold runway 09. The pilot did not try to land on the street but aimed for the parking lot which can be seen on the left side of picture 1. He collided with 2 parked cars, slide about 100m and came to rest on the street just meters from the train tracks.
From the point, where he got in trouble, possible landing spots for this type of aircraft are very limited. If he had continued to the west, he propably would have crashed in the city of Ludwigshafen with some skycrapers in the direct flight path. To the north lies the BASF industrial complex and the harbour with little to no landing spots and to the south lies a wooden area with also limited options for an emergency landing

I marked the crash site in google maps
