The faq for this part says: "When a helicopter appears, blow up its silver windshield."
I'm unable to do this. Batman's in his power suit, but I can't target any part of the helicopter. The windshield also doesn't really appear to be like other silver things Batman can blow up. Chucking bombs toward the copter doesn't work either. Superman's heat vision/freeze breath is also a fail. Is this a glitch? Has any body else experienced this with the 3DS version?
As it is, it looks like I'll have to wait for a patch to get through this part of the game, and if nobody else is experiencing this problem, that patch probably isn't coming.
