B720 Question

Fri Aug 20, 1999 11:38 pm

What's the difference between a 720-020B and a 720-047B?
Thank you. Hisham.

Hi Hisham! There is exactly no difference between those 2 models, normally Boeing uses the last 2 numbers or a mix of one number one letter or even two letters to identify their customers, for example the 047B was the 720's sold to Western with the B meaning a turbofan version, another example was the 022 version, that was a trubojet version sold to United! About the 020B that's the Boeing identity!
I hope I answered your question!

None as such. The B720-020B (none of which, I believe, were built) would be a Boeing company aircraft and Boeing didn't have any corporate 720s or aircraft used for tests. The numbers after the dash refer to the aircraft operator, all Boeing operators having a code, starting with -21 for Pan Am (being the first jet operator. -22 was United's code and it was the first B720 operator, although its aircraft were just the standard -22s, not "B"s. Western's (-47)aircraft were higher gross weight models, or "B"s.

Hi Kaitak! Although none B.720-020B was builted the 020 is the code for Boeing, I'm sure that Boeing when was marketing the plane was refering as 720-020B, and if Hisham talked about that is because he saw any reference of that, perhaps in a book of something! Also when you spot a B. 707 if you don't know exactly who ordered the plane first you reffer normally to a 320B or 320C or 420 or a 320 right? If you look to B. 707 c/n 20008 registration N707N was a 320C model and it was sold to Varig also as 320C, not 3 then 41 ( personal number for VARIG ) and C with side cargo door.
So the 20 exists for Boeing! Also did you know that USAF as also their 2 number digit in Boeing? Yes, it 53!

How do you explain then the fact that Middle East Airlines(MEA), in their 1979 annual report, state that they have 12 B707-020B and 4 707-047B? If these aircrafts are the same, then they must have the same name with the same customer. The same designations are used on this site for 720s of MEA and other airlines.
Hisham.

Yes CV990, you are quite correct, but reading over what I wrote and re-reading what you wrote, maybe what you thought I wrote wasn't quite what I actually wrote, well, you get the general idea . . .

What I did say was that there was no difference and that no B720-020Bs were built, which is still correct. They existed on paper and the generic models were called the -120, 220, 320 etc, but none were built as such. The ones which were built actually carried the customer numbers.

But point taken . . .

In reply to Hisham's question, I'd say the answer is that all of MEA's 720s were then ex-Western, but not all of the 707s came from the same source (incidentally, should that read 707-320s, not -020s?). Some came from American, one from Western and a few came to the airline directly. The latest JP still shows about six in the fleet, awaiting sale in Beirut.

Hi Hisham. As I can see MEA did a mistake when they said there were 12 B. 720-020B in the fleet, because as Kaitak said MEA received 13 B. 720-023B from American Airlines and 5 B. 720-047B from Western, but they didn't received any new from the factory. Another interesting fact is that from the 13 received from American 5 were first 023 with turbojets but in 1961 they were returned to Boeing to be converted to B model with turbofans and a small ventral fin added! I wanted to tell you this because if for any reason you will see one day a 720 from American photo that latter was in MEA you don't be confused because some of them came first with turbojets!
Have a good weekend!

Kaitak, 720-020 is the newer name for what was originally called the 707-020. I was not referring to B707-320s. So when MEA says it owns 707-047s, it means 720-047s. So, as CV990 said MEA got its 720s from both American (I checked it) and Western (as he said). But MEA made a mistake when it stated that is owns 12 B707-020B and 4 707-047B. It should have written 12 B707-023B and 4 B707-047B. Or 16 B707-020B without specifying the customers that originally owned the aircraft. I think the second option is the best one because it avoids misleading the reader that these are different airplanes, specially when the origin of the airplane is not relevant.
Anyhow MEA 720s don't exist anymore! I know that the last two -023Bs were sold in 1995 to Pratt&Whitney Canada to be used as flying testbeds. Another one has become a restaurant near Beirut! And as Kait tak said, MEA still has 6 707-320s for sale, but they are not used anymore. It is now 100% Airbus. 2 A320-200, 2 A321, A310-200 and A310-300 (I think the total number of 310s is 7). All are leased. Last year they sold their 3 747-200Bs to American International Airline.
Thank you guys for the help! Hisham.

ps Where did you find the information about MEA?
