Then it was Tuesday 20 October and we could start doing our thing. We drove towards Seongnam early in the morning. There was a lot of traffic on the road, so we had plenty of time to have a look at the huge quantities of anonymous and ugly appartment buildings. Without too many challenges we could enter the terrain of ADEX 2015 rather early. We wanted to be here on the day of the official opening ceremony since that ceremony always includes a impressive fly-past by the Republic of Korea Air Force. It was rather hazy / misty / smog-like today and the sun had a hard time breaking through. The Slam Eagle that performed 3 passes in the morning as some sort of weather flight, was hardly visible. Slowly the weather started to improve bit by bit and the Seongnam based aircraft did take off to take part in the fly-past. Eventually dozens of ROKAF aircraft (fighters, trainers and transporters) showed up from the stuff in the air. After the official opening the home-based aircraft started flying again too and we were able to capture a fair amount of transport and VIP aircraft as well as choppers. The limited flying program, only in the afternoon, was cancelled due to the weather. The USAF F-22 Raptor did take off but only made a couple of disappointing passes. Nevertheless it was a nice day, also due to the Seongnam based aircraft. Among other things we saw two ROKAF Hawker 800 / BAe125 / RC800s. At the end of the we managed to be allowed to remove the ribbons around the ROKAF F-4E in static display. The day ended with a traffic jam, a BBQ and a beer.
