5. Delta named their first DC-9-10. What was the name given to this aircraft? Hint: think "royalty"
I was unaware Delta named its aircraft except for the occasional special exception such as "Spirit of Delta". That said, a royal name you say...
How about "Delta Queen"?
The DC-9 seems a bit small to have "Queen" status bestowed upon it but what the heck - it's a starting point...
