Spelling & grammar are overrated
No, they are not. The ability to spell and to structure a sentence correctly is a clear indicator of a person's intelligence and standard of education, both of which I consider to be important prerequisites for anyone considering a career in aviation. Granted, I don't plan on writing a literary masterpiece any time soon, but I still consider it important to be able to distinguish between "to," "two" and "too." Unfortunately there are many on these forums who do not, or worse, can't even tell the difference.
Language and the ability to effectively communicate ideas in verbal and written form, along with the capacity for imagination, are all that set us apart from the rest of the animal kingdom.
Rant over (and apologies for perpetuating thread drift).
