Well done
So what else has every Vbase have in common?
If you can't figure it out now you never will.
You could easily use some basic trig to hit the other structures, provided you have an exact range. But that's the kicker, since minutes and seconds of degrees matter at long range.
And you couldn't use the range in the gun sight, even if you were close enough to see the radar tower from the gunner position, since that would only give an apparent range, not true range.
I'm not questioning the theoretical possibility of it; I never have. What I question is the practicality given the measurement error involved.
