Martin WB-57 (N926NA)

Designed and built in Great Britain as the English Electric Canberra. Built under license in the USA by the Glenn L. Martin Company.

This version first flew in 1963 and was called the RB-57F, It saw extensive service in Vietnam. Later converted to the WB-57 for NASA. A total of 21 '57Fs were built.

It is interesting that some of the older model planes just keep flying and getting the job done. This one, the DC-3/C-47, the C-135/KC-135/RC-135, the C-130 in all of its various models, and many others.

Great Catch Brendan! Never seen this one before. Thanks for posting it.

Oh! Canberra!
It saw for the first time.
Thank you for the publication of the photograph.

Nice shot of this strange hybrid

Very distinctive odd looking aircraft - love it

Fantastic photo!

Speed and max altitude?

I had many an interesting conversation with a Vietnam era pilot of this amazing aircraft.

Flies over my house all the time. I saw it this morning. Engines are typically sooty for their age, but unusual for what we usually see on most aircraft flying today. It's super noisy and high-pitched too - very distinctive. A couple of the pilots tweet regularly, @NerdyKowboy and @nasawb57

Great shot! An amazing example of 're-purposing' an already good design into something 'special'.

Seen this one in her hanger at EFD up close. Also watched her flying in and out of EFD many times. Engines have a high pitched “whine “ about them and fluctuating up and down in pitch just to maintain speed I assume. Very cool recon machine with very limited room for pilot in space suit…

We had these birds at Forbes Air Force base in Topeka Kansas in 1970.
I was told then that they were Australian Air Force. They only had the engines on the wings then as I recall.

I build a model of a B-57 as a kid and in 1970-71 I saw the ones used in Vietnam at Tan Son Nhut AFB (Saigon). I loved the look of it.
