I have flown into Hanscom several times over the last 30 years. Its civilian and AF mix. Raytheon is nearby and a host other defense contractors.
Very good ATC although if you are not familiar with the locale it can be enlightening.
A familiar instruction is "Turn left at HoJo's"
Alright if you know Howard Johnsons has an orange roof!
Don't recall any foam or other stuff at end of runway.
It's a very busy airport but very well operated. My take!
