    Sorry GB, but don’t understand how that tuft placement would help investigation of gas flow into the engine bay. Having now had the sense to blow up the image, I see it had an exhaust shroud fitted – my belief is that they were just checking for airflow from a modified exhaust shroud. Understandable given the design of the exhaust stubs and the original shroud. This shroud would have also had benefits in reducing visibility at night.

    I love your statement: ‘flutter was understood’. I think I have a ref to flutter in a 1912 book in my collection. The basic ‘mechancs’ of flutter are understood, but flutter is never fully understood….it is like a chameleon (specific to the application)…it still catches people out…..it still needs some odd fixes….

    And regarding chase planes…..A&AEE would (and continues to) use a multitude of aircraft types (whatever is available) for photochase….not just a Hampden.

    the above posts cover the areas that the Tyffie suffered from well. But I cannot see how the tuft tests would aid either: The tufts only serve to show local airflow patterns. For Carbon monoxide, I doubt the tufts would be much use. Even in those days, they had an idea of flutter. I have a report, somewhere on various structural fatigue issues etc that RAF aircraft suffered from; it includes the Typhoon and has several crash investigation pictures.

    Tufts are useful to look for airflow breakaway, and turbulent airflow. A photo chase would be required. I would look for a handling qualities related issue driving the testing, something like handling in stall/spin. The nose is interesting. It is a big old nose….the tail/rudder is big too (needs to be). Sideslip tests would show blanking…..just kicking a thought ball around!

    yep the forum is a funny place!

    The top question I get asked, either at the museum, displaying at a show, or in an aviation environment is about the Burma Spits too TO!!! There really are a lot of people who believe there are enuff for all of us and that just kick the tyres and put some gas in!!!
    Back to subject, the frame 5/6/7 section with wing stubs looks very nice

    Many thanx for leads. Jason, since the longerons wont fit your tub! Can I buy yours/trade??!

    As my project already has an identfication, there would be no provenance issues. So please restorers out there…please help a static P51 join the ranks?!

    whilst i understand that some don’t want another BoB program, don’t take it out on the Few Mr Blue Max!

    I am keen to see any program/series that raises the profile of any allied aviators.

    I would love to see something on Coastal Command – not a chance

    a piccie of PZ865 shows the same cowling ‘panting’ just before it flew off about 15 years ago

    Sad they did not ask. I am sure most enthusiasts would let them use their phots for free with suitable credits.

    Up to now words were beyond me. Thanx for posting of this moving film and the story of name behind the face. What a real life hero – in peace and war time.
