In a real B737 cockpit, one can see that the metal plates on various places are attached with special nails with round head (rivets?).

To the idea and example of Jan Willem Severijnen, I have my cockpitvloer also equipped with the necessary ‘body piercings’.

With photos of the real I tried the cockpitvloer in the right places with nails. In total, I have 342 nails ingeklopt.
