Surely a study of DVT amongst airline pilots would be the best bet of finding out if there is a higher risk for air travellers. Who else flies as often as we do? We already know that media luvvies only call it 'economy class syndrome' because they are the lowest denominator when it comes to catchy 'themes'. In reality we know that DVT affects passengers from all classes of seating.
I know of some pilots who have suffered from DVT but surely a study of the number of cases amongst the airline pilot population as a whole would be the most sensible course. After all, we come in all shapes, sizes, colours and ages. Why the media luvvies or anyone else haven't mentioned this yet baffles me.
