Roslindale is all atwitter tonight about a small plane that is just circling the neighborhood over and over (I'm hearing it as I type this, sounds like it's somewhere in the vicinity of Metropolitan). Why is it up there? What does it want?

UPDATE: BPD says it's a "mapping plane," which they know because people have been calling them and somebody there checked with Logan. Makes sense, because you know how much Roslindale's streets have changed recently - although somebody less of a jerk might suggest things other than roads can be mapped. A source says this is the plane.
