Tower closed and surcharges are imposed between 2300L and 0700L.
If you want to get a status report on runway conditions you can call "Hanscom Operations" at 617-212-6592, you can also text them at that number. They will also respond to email@example.com. They man these contacts 24/7.

Airport Risk Analysis
There are ILS approaches to two runways, LPV approaches to three, but no instrument approaches to one. There tends to be a lot of small airplane traffic during fair weather days.
From the Gulfstream Noise Information Manual: "Nighttime operations permitted but an environmental operating fee will be assessed for each operation. Charges will be doubled for any nighttime operation by an aircraft in excess of five nighttime operations in a particular calendar year." For a G-450 in 2013 that amounts to $412 per event for the first five events and then $824 per event thereafter.
Class B Considerations
The airspace below 3,000 feet from the center of the airport towards Boston underlies Boston Class B Airspace. From the center of the airport to five miles west below 4,000 feet also underlies Boston Class B airspace.

Runway 05 is over a small hill and requires a steeper gradient, the VASI is angled at 3.75°. There are no instrument approaches to this runway.

Runway 23 takes you over a residential area and a small hill, the VASI is angled at 3.5°. The only available approach is an RNAV(GPS) without LPV minimums, but it allows C073 OpSpec/MSpec/LOA holders to use VNAV DA in lieu of MDA.

The visual to Runway 29 can be difficult in some lighting conditions because of the surrounding lights and three towers on base to final.
A normal two mile final will not work because of the towers. Adjusting the normal pattern math for a 2-1/2 mile final helps. Enter the pattern with a 2 mile offset, heading 110°, corrected for drift. 2,000' MSL works well. 200 KCAS and clean will work through midfield, then 180 KCAS (Flaps 10°), and finally 160 KCAS (Flaps 20°) when abeam the approach end.
Look for the three towers on base, extend the landing gear.
Turn smoothly to base when passed the towers, adjust pitch to achieve about 900 fpm descent. Roll out 200°, check altitude around 1,500 feet and look for runway to judge final turn.
You are shooting to roll our on a 2-1/2 nm final about 1,000 feet MSL.
Pitfalls (mistakes I have made):
- Turning over the towers — creates uncertainty in the descent rate.
- Rolling into the base turn too briskly — can place the aircraft over the towers.
- Failing to roll out on base — placing the towers on your right gives you a healthy 2 nm downwind displacement. A constant turning base will roll you out well inside final.
- Failing to identify the runway end on base — the tower tends to run the lights at a low intensity; don't be afraid to ask them to turn them up. Knowing the relationship to Highway 128 can help too.

How about left-hand traffic? (Click for video)
The traffic into and out of KBOS impacts the departure corridor from KBED. Expect to fly north to MHT on the way west.
