Another Note
The man indicated a bed with his finger. But in addition to that, there was something else. Another note was located on the head of the bed. Because of all of these notes, Philip had the impression that he was participating in a treasure hunt. Why did this person, who clearly was aware of the location of the plane, not just go there themselves?
Coordinates Were Found
The note had the coordinates written in it. Because Philip is skilled at reading coordinates, he has a general idea of the direction in which he should travel. Philip was confident that the location the coordinates pointed him to hold the airplane. Therefore, he continued his search with an optimistic attitude the following day. But he never in a million years would have predicted something like this.
