Bearcat F8F, you'll have to look at the Canadian and US immigration sites to see what's required. From what I understand, the US requires a "green card" (enter the lottery) and you'll need to convert your licence. Mates have said it can take quite a while to jump through all the hoops. Canada, not so sure on their requirements.
Flying in Africa will require Air Law etc. It does depend on the country. Again, look at the individual state's requirements.
Back to the show. I'm enjoying it. It's reminding me of the flying I did in Oz.
Of course a lot of it is probably "to camera". I am astounded that people think it's acceptable to rock up to see the Chief Pilot in a t-shirt and thongs/flip flops. I sincerely hope that was a set piece and not genuine.
Top tip. Have a look at what the working guys are wearing and mimic that standard. It's the least you can do.
What it is highlighting is that the work won't fall into your lap.
Any way, it's fun.
