Ton up

When I was a kid doing 100 mph in anything was impressive. Later, flying in Concorde and watching the huge bulkhead sized display confirm that we we going faster than sound was pretty impressive too.

So I love this little app on my iPhone which simply polls the GPS
satellites to see how fast I (or more precisely the phone) am / is going. So here I am (nice screen grab feature built into the iPhone by the way) on the Heathrow Express doing a quiet and unflustered 100 mph. It really IS an express!
