What approvals do I need for a helicopter landing? I have a horrible conflict; my sons are graduating on the same day at about the same time in different states. One in East Greenbush NY the other in Beverly MA. 

I am interested in hiring a helicopter to transport us from NY to MA. My question is if I receive permission from the schools to land what other permits or steps would I have to take?
If you charter a helo, most likely they’ll fly you from KALB to KBVY, then provide you additional ground transportation to and from these airports.  As to landing directly onto school property, that would probably be at the discretion of the school itself; my guess is that they would frown on it unless it was an emergency, as helicopters are a noisy and somewhat dangerous nuisance to have around.
