What serendipity!
On a more serious note, having never flown F, I admit to being shocked that BA haven't followed
François Rabelais's recommendation on the best material to use for this purpose:
there is none in the world comparable to the neck of a goose, that is well downed, if you hold her head betwixt your legs. And believe me therein upon mine honour, for you will thereby feel in your nockhole a most wonderful pleasure, both in regard of the softness of the said down and of the temporate heat of the goose, which is easily communicated to the bum-gut and the rest of the inwards, in so far as to come even to the regions of the heart and brains.
