Rachel Audi just posted the following:
This afternoon before 1 and 2pm on WAMU 88.5 FM, Sabri Ben-Achour and Sylvia Carignan will be doing a final report on the booms we hear in Cheverly. After the report, it will be accessible at http://wamu.org/programs/mc/11/01/21.php#40134.
Click on the link and, besides a lovely photo of Rachel, there is a pretty cool map of reported booms.
