Re: USS Iowa - that's what pennant numbers are for in US Navy. I mean, there's rather a visible difference between BB-4 and BB-64 (yeah, I know it's not Iowa but Wisconsin, but still the same class
). And is the making those few mouse-clicks to look into the picture itself such a horribly hard work?
Re: everything else - how do You imagine implementing the changes You demand?
Especially on the works already made? 2013 database overhaul took several weeks to do to several of us, so who is supposed to do these changes only You
seem to demand?
In most cases for all these real and never were drawings, Wiki has some info that you can just cut'n'paste or the book you got the scan from will have data you can transfer.
Well, I'd say that equally well the person who is unaware of things like "what era it represents" or "Date of entry to service, even prototype first flown, last flight" may try to be less lazy and simply use Wiki or Google to find out.
