If you think air travel sucks now, Imagine airlines having to bring their plane to Boeing every time it needs new brakes on the landing gear, or having it rot on the tarmac in Kuala Lumpur waiting for the AirBus repair team to come replace a wiper blade

Fortunately, planes are designed to be serviced, and the manufactures make replacement parts available. Going further, the manufacturer even publishes instructions on how to service the plane as well as tests you can do so you can make sure the plane is operating within specifications.

I don't see why a med tech company couldn't do the same so a hospital can fix its own hospital bed
