Suspicious Search Pattern

I wanted a sample blueprint that I could show kids as a sample floor schematic.  I searched for vectorized drawings of houses and such but found nothing and started looking for neat stuff with blueprints like fighter jets but also found little so I started looking for hi-res pictures of famous buildings.  I searched around a bit and finally stumbled upon a nice schematic of the White House.  I failed to save it properly and went back to Google to get it again when I noticed Firefox’s history of search terms:

white house blueprints exploded
white house schematics
how to build a missile
missile schematic
soyuz capsule filetype:eps
pentagon blue prints
pentagon schematics
monument drawings
famous building, exploded view

I wonder if DHS takes Cub Scout program into consideration when reviewing search history…
