Patrick Weidhaas remembers:"The 1950s and 60s were an exciting time in Tempelhof. I was a "teenager" and explored the old terminal from end to end with my first camera, an Agfa Box. The photos were taken by me in 1958 -- I was 16. One or two years later, I mustered all my courage and headed to the US Air Force offices, where I brazenly asked in my best English if there was someone who could give me some detailed information about the GCA (Ground Controlled Approach) landing system at Tempelhof. A nice officer asked me to come back in three days; it was an icy-cold day in January or February. The officer led me to a "Follow-Me"-Jeep and then we drove across the icy tarmac to the eastern threshold of the southern runway (near 27L). There, the mobile GCA truck trailer was located; inside it was dark, 2 or 3 air traffic controllers sat in front of greenish-illuminated radar screens and communicated with landing pilots. In a calm, quiet voice, they informed the pilots of any deviation from the glide path. This was the system that had passed its first major test during the Berlin Airlift. This visit to the GCA truck was an experience I have never forgotten."
