Was The B720 The Same As The B707?

Sun May 22, 2005 9:37 am

Hi,

I just saw a picture of an old Eastern Airlines's B720 [unfortunately gone] and it looks like almost equal than the B707.

Were [are] they "basically" the same aircraft?

Thanks in advance for all your answers.

As far as I know, the 720 was a derivative of the 707 with less range and a shorter fuselage. Please correct me if I'm wrong.

Cheers,

The B 720 had a shorter fuselage than the 707. I was lucky to fly one in 1976 in South Africa. I think it was from Jo'burg to Victoria Falls (former Rhodesia)

The wing was also a slightly different design.More like the KC-135 (Model 717) wing.

The B720 was designed to counter the Convair 990 ...

Fuselage on the 707-100 and 720 were the same (if memeory serves...)
The wings however were totally different, to allow for a higher cruise-speed.

They were swept back more than on the "standart" 707....

If I mixed things up...(which I hope not..) sorry!!!

Godspeed

All in all, I have 8 takeoff/landings on B720B. 6 in 1983 with danish charter airline Conair, 2 in 1985 (Danish charter airline Conair) and 2 in 1990 with Kenya Airways. But 0 in a real B707.

I know that the B720 have been called B707-020 in its very early days. So where can I fly a really B707 ?

Regards

Quoting FBU 4EVER! (Reply 3):
The wing was also a slightly different design.More like the KC-135 (Model 717) wing.

The KC-135, 707-120 and 367-80 shared a common wing. The 720's inboard wing had a leading edge glove that improved the high Mach number drag. The 707-320 wing had a root plug added, along with a new leading edge.
