Even that article clearly explains in the first paragraph that the corridor
is NOT closed to fixed-wind aircraft. If one reads the actual NOTAM, one
will see that amphibious fixed-wing aircraft operating at the seaplane based
are also permitted (why amphibious and not any seaplane, I don't know), even
without ATC approval.

An odd exclusion, seeing as we always had to contact LaGuardia tower
when inbound from Easthampton into the 23St seaplane base. The Throg's
Neck routing had us overfly LGA's tower at 1000ft and then a direct
turn to the power company building (Big Alice) then switch to river
frequency and announce the descent & landing. It's unimaginable that
you would even attempt to do this without ATC contact - even before the
accident.
