The MA ANG F-15s out of Barnes were working in the Viper airspace this morning, would have flown right over your location, you would have been able to hear them on their air-air, Operations and the Boston Center UHF frequencies.
If you hear any other frequencies please post them here and we can figure out what they might be.
