I see how it is done, although I dont know how that can be safe - you're head is resting on the seat in front of you; fine? But you're legs are just going to snap on impact? I see the Virgin video wants you to tuck them slightly under you're own. But to me, getting them to rest on the seat as well might be a good idea?
I am a tall very thin man, and anyone else who is either tall, has a big belly, or is overweight - would have great difficulty!
I read the safety card all the time, it's just not very clear.
