..still amazed that my car has run flat tires, but planes don't. More
60's technology flying around. Astonishing.


What's the speed rating on your run-flat car tires? How often do they need
to go from a dead stop instantly to 60 mph or higher? Do you have any idea
what it takes to get a new aircraft product certified in terms of money and
time?
