The plane took off again, this time carrying two inflatable boats.
The mission was still reconnaissance, but it wasn't limited to aerial surveillance; they needed to scout the ground.
Since it was a reconnaissance and not combat mission, the only course of action upon any sign of human activity was to evacuate, which is why Gao Guang and his team didn't carry much combat gear – just five pistols, along with two AKs, and that was all.
As for reconnaissance equipment like radar, telescopes, and thermal imaging – these devices were useless due to the extremely dense vegetation which blocked everything.
Those from the south, especially the tropics, would definitely understand what such dense vegetation signifies.
In the rainforest, having a visibility of ten meters was considered open; normally, it was impossible to spot a person hiding just one bush away, less than a meter distant.
