Gao Yang went to inspect the airport that now belonged to him.
It's a bit of a stretch to call Beira Airport an airport. There's basically no ground control system, no radar, just a few high-power radios that can communicate with airplanes in the sky, and a runway on sandy ground. Of course, there's no condition for night landings since there are not even indicator lights on either side of the runway; pilots would need to dare to land blindly at night.
But in any case, Beira Airport can accommodate An-32 planes taking off and landing. With this airport, Gao Yang can use air transport for urgent situations to Yemen, whether to transport people or things, it's feasible.
Of course, the port is the most crucial part. Controlling the port means arms can be continuously delivered to Beira, which is vital. Originally, the Skull Gang had to launch an attack on Beira from Bosaso, transporting arms over long distances, mainly launching attacks from land, making supply a major burden.
