So, it’s possible that the plane is a problem for the Cohen, and a bag might help, but no way is that the solution?
Remember, the guy didn’t ask for his picture to be taken, and he wasn’t holding by travelling by boat, and this helps.
The only thing that I still don’t understand is what I asked earlier, if a bird carrying a Kezayis Mes is not Maahil, bacause it is an Ohel Zaruk, why is the Cohen, when he is Zaruk, considered Maahil?
