Map of flights at specific time in the past?

[dtgriscom]

I have an office in Wakefield, Massachusetts. Yesterday at 10:40AM (EST), I suddenly heard a LOT of helicopter noise. I checked my PiAware site, and there were four helicopters in the area:

I neglected to grab their idents, so I can’t directly view the flights now.

Is there any way to see a general map of flights in an area at some time in the past?
