Some things never get old.
This an excellent example of why you should always proof your work. Granted, the word is technically correct, so I can understand how this mistake might have been made. Read the next paragraph to discover just where this little typo is.
The shuttle’s name is not “Endeavor,” but “Endeavour;” its British spelling reflects the fact that the ship is named after the HM Bark Endeavour, a 10-gun Royal Navy bark commanded by Lieutenant James Cook on his first voyage of discovery to Australia and New Zealand in 1769-1771.
So this is just your basic typo … printed in about 500-point type. Embarrassing, right?
I think USA Today may have said it best with their headline: “Houston, We Have a Typo.”
