You are right, SR-71 in NY will not be possible. But there are plces like Air Force Armament Museum - Eglin Air Force Base, FL
or Beale Air Force Base, CA
where it may be possible to take some measurements, at least theoreticaly. Perfect solution would be to have someone from museum staff on the task

. I knew one such a person, but unfortunately he is not working there anymore for a few years and mooved out from the city

Thank you for the plan Zathros. I wish it would be as easy as scale some plans. I tried this NASA public plans and they are just schematic drawing, not fitting at all. I also tried lots of different plans from other sources, mainly books about blackbird planes, but none was consistent match. Some pats of the drawing match and other does not, so scaling to known dimensions can not be trusted. But I have some Lockheed plans with quite a few dimensions and other infos as wing chord and tip lengths, incidence ange, wing sweep angle, fuselage diamettr etc. They seems to match, so it helped me tremendously. Unfortunately engine nacelle is not covered by exact dimensions on thees plans and its drawing and angles does not match the real thing and are also distorted by their scaning/copying.
So I am using photos to guess remaining dimensions. It is tricky due to lens distortion and croping of photos unknown to me. Some actual measurements would proove/disproove my guesswork
