A friend - a headmaster at a local school who I'd shared the info about the shuttle/IS transit with - phoned me to share excitement just after it flew over head.
Does he know, that one of the astronauts on board is a 55-year old schoolteacher, who was the "standby" for she who died in the Challenger distaster? Who then succeeded in joining the astronaut corps, and is now up there? She's got a job to do (mostly working with the robot arm), but she will be "teaching a few lessons from space", also.
