Not too bad.
The magnetic field nearby is quite strong.
When the helicopter arrived, it didn't use radio signal navigation but reached its destination by observing the terrain.
Otherwise, if we assigned these clumsy folks on the ground a surveying task and had them come over with coordinate measuring equipment to report the aircraft's position, that helicopter would definitely have ended up in a ditch today.
Fang Huai felt inwardly that the helicopter instructor from the past two sessions might as well have been invited for nothing when he saw everyone spotting the helicopter, yelling, and waving their hands towards the sky.
It has to be said, Hu Peizhou's method of selecting people with higher vocational education qualifications has its drawbacks. Each one learns rope techniques awesomely well, even copying notes on helicopter ground signal flags, but when it really matters, the knowledge flows through their minds yet remains as pristine as if it had never been there.
