<div dir="ltr">With this issue coming up again with the publication of the picture of the Kohen in his bag on the plane (<a href="http://4.bp.blogspot.com/-xF1pWneGukU/UWZvRrEd8kI/AAAAAAAAF14/X01JD3HtA6k/s640/bag+on+flight.jpg">http://4.bp.blogspot.com/-xF1pWneGukU/UWZvRrEd8kI/AAAAAAAAF14/X01JD3HtA6k/s640/bag+on+flight.jpg</a>), a few questions came up:<div style>
1. The 787 fuselage is not made of metal but carbon fiber reinforced plastic which is not mekabel tumah. I would guess that in the future more planes will be made from this material. Would this mean that there is no problem flying on this kind of plane?</div>
<div style>2. There are Jewish cemeteries all over the place, especially in the US and in Europe. If you fly from the US to Israel over Europe for example, how can you possible know if you are flying over a cemetery? Can you simply go with rov? </div>
<div style>3. Does it matter at what altitude the plane is flying at? I know we say that tumah bokaas v'oleh ad lashamayim but does that include a plane flying at 35,000 feet? What about someone in orbit? </div></div>
