-I don't know if this Boeing 720 is still active, but on the subject of noise regulations I think this aircraft is exempt, because it is operated as an experimental aircraft. The last time I saw it in the UK, it had a sign by the entry door, stating that it operated without a certificate of airworthiness. Although it is/was maintained to an approved maintenance schedule.

-Is this the same reason that John T's N707JT is allowed to operate in its current configuration?
And I take it that an airline or cargo carrier is not allowed to operate under as an experimental aircraft?

-A lot of 707's were fitted with 'Hushkits' to meet the 'stage 2' noise requirements & a few have been further modified to meet the current 'stage 3' requirements.
The 707-100 required less modification to meet 'stage 2', due to its better field performance & I assume that N707JT is up to 'stage 3', although the engines dont look any different from the 'stage 2' modifications, to me anyway.
C-FETB had no hushkits.

I think they are, I seen a pic of an American Airlines 757 which noted that it was flying commercially with an experimental certificate.

-Perhaps the B757 didn't have it's Certificate of AirWorth at the time...
Are the B707 commericals no longer allowed in the UK?

They are only allowed if they are 'stage 3'. The only ones I have seen this year are N707JT & Lowa's N88ZL. Air Memphis freighters are also 'stage 3' I think. Sometimes, relief flights get an exemption.

-Rare creatures indeed......
It would be nice to see a 707 kept flying in a Pan Am scheme for future Airshow goers..just like the KLM Connie etc...but the cost of keeping a 707 just for that reason would be $$$ huge...

That is why we need enthusiasts like John Travolta. :)

-C-FETB is the last airworthy 720 in the owrld. Hands up who remembers the Monarch and Air malta 720's?
These are banned in the EU along with DC8's, BAC111's and IL76's. Although 76's do operate aid flights with special permission. This 720 would need special permission to operate too. I guess the RAF VC10's and MoD 1-11's are exempt?

the noise military aircraft make... it would seem any currently active military aircraft is exempt.

Pratt & Witney used to operate a flying test bed Boeing B707 023B cn 18024 regn C-FETB.....does anyone know if it is in use out of Dorval - Montreal Canada these days? or has it been retired or moved? It still appears to have a current regn.
And if so how is that they are able to operate given the noise regulations in effect these days in North America?
707 Fan......
