<p>I made a mistake in this שיעור. While I have not found any source that says that אהל זרוק is still able to be מביא טומאה, the הלכה is that something that is מקבל טומאה is not חוצץ בפני הטומאה but IS מביא את הטומאה. It therefore follows that if the מת is not in a separate plastic compartment (body on any plane besides for El Al), and we are relying on the floor to be חוצץ בפני הטומאה, it would be a problem while the plane is grounded because the ceiling is מביא את הטומאה.&nbsp;</p>
