Poor analogy - the 737 engineers conduct their work on the ground. To do any physical work on Hubble, it is an astronaut's EVA skills that are required, plus the vehicle to get him to the work site. Mr Anderson has 38 hours EVA experience.
Now, fantastic things have been done remotely to space probes' computer systems, remotely updating software, routing around malfunctioning modules etc in the past. Let's hope engineers succeed on this occasion. Even if they do though, eventually Hubble may need some new components fitted.
