I kind of doubt it ,as it looks like checklists . But that little piece of stuff that found it's way onto the canopy might be a different matter . I'm pretty sure Maintenance would have heard about that . It's an Iron clad rule that if You drop something in the cockpit ,it has to be retrieved . If You are ever seen to violate that rule , You're stay in maintenance will be short !do you think the pilot got in trouble for the papers flying around inside the cockpit ?
