Travellers' Deaths

Sta,—Professor Brogan says he has seen the statistics which prove that air travel is safer than road or rail, and doesn't believe them. I think I know why. The airlines say that in each mile you travel by air you are less likely to be killed than in each mile you travel by road or rail. It would be more reassuring if they could say that each time you take off you are less likely to get killed before your journey's end than if you had gone by road or rail. " Accidents per passenger-mile " is the figure they give us. Could they not give us " accidents per passenger-journey " ?—Yours faithfully, W. HILTON-YOUNG. Leinster Corner, Lancaster Gate, W.2.
