Or even the Model 7, a float bi-plane from the 1920s. But a lot of the prop jobs had other ending numbers, and all the jets both start and end with '7', except for the above 720. Except for 797, all the other numbers from 707 through 787 have been assigned so I wonder what number system will be used in the coming decades?The "xx7" designation goes all the way back to 1933 and the 247.
Dating myself now but I got that reference!and watch out for bulldozers.....
