Q.When the body itself is buried, do the severed and saved body members, require to be buried with the body? How are they to be transferred to Eretz Yisroel?
A. See question 3407 above that when possible they should be buried together with the body.
Most Poskim maintain that utensils that themselves can receive and became Tameh, such as those made of metal, even aluminum and similar, cannot become an “Ohel” or tent to separate between the body and the site of the Cohen in the plane. An additional and similar issue applies to a “Ohel Zaruk” or a traveling tent such as the plane itself and everything inside it. (Minchas Shlomo 72. Igros Moshe Y.D. 2: 164, an others).
El Al has acquired additional boxes made of cardboard or plastics that do not receive Tumah themselves and according to Poskim they will separate the dead body from the rest of the plane and thus permit Cohanim to travel in the same plane. Therefore one is allowed to send their dead relatives on that plane to be buried in Israel. (Miyam Hachalacha 2: 48 and others.
Horav Shlomo Miller’s Shlit’a opinion is that the severed and saved body parts should be send also inside similar containers if they could not be transferred together with the body.
