Polish head of state plane crashed in middle of nowhere? [56]
It was dense fog - bad visibility.
Airport had no instrument landing systems capability (ILS), necessary to land with very poor visibility.
Pilot circled around few times, probably getting a good feel of the marker beacon signals, which give an indication where the runway is.
Pilot thought that had good altimeter settings - maybe he did, maybe he didn't. That one I would like to know.
Pilot probably planned to come in little low, so he can spot the runway sooner.
And most importantly, Pilot thought he could land the plane.Every pilot knows that final decision is his, and his alone.
