Do you really want the attention that comes with "technicalities"?
Technically, if flying, you would be flying over NYS instead of through it - still not legal.
Went up to SW NYS with my g/f and mom to do some flea-marketing, not too far in, but just a couple miles over the border w/ PA. Could I have gotten away with taking my weapon with me either on my person or in the car? Actually, yeah, i probably could have - didn't see one cop the whole way. Would the penalty be worth it? Nope, not a chance. Took my usual knife and baton and went on my merry.
