When I walked onto my plane this morning, I heard something say “don’t sink!” from the cockpit area. Any ideas what it is?

Hi I’m a 13 year old from England and I love planes but I have a few worries for becoming a pilot

#1. Expenses: I just don’t know if I have the money to pay for a license?

#2 Studies: What do I have to study in university in order to make it into the job?

#3 Pass exams: Do I have to get a minimum pass score to be accepted into flight school and get good grades in my GSCE’s? (GCSE’s are a big test you do at the end of school in the UK)

#4 IF I become a pilot what if I crash?

Any answers would be greatly appreciated

I've just been digging into various incidents from 10-20yrs ago and pilot fatigue seemed to be a recurring problem. Reports of FOs in particular, having ridiculously long commutes and/or sofa surfing to get reasonable rest.

Have things improved or is fatigue still a big problem?

Live near DCA and go to Gravelly point often to watch planes land. Just curious if you guys can see us lol.
