- I don't think the ASTP orbit was close enough to Skylab's to make this
- practical. I believe it was structurally possible.

- Mind you, most of the science community thought the hardware and money
- that went into ASTP would be better spent on another Skylab crew... and
- they were probably right. That might have provided a suitable opportunity.

- It's important to bear in mind that, with program plans and air-drag
- forecasts as they were in the mid-70s, it was clear that Skylab would
- not re-enter until well after the shuttle was flying and something
- could be done about it. There wasn't any feeling of urgency about
- reboosting Skylab. Then the US scrapped its remaining manned-spaceflight
- capability, the shuttle schedule slipped repeatedly, and air drag
- ran well ahead of schedule... The Skylab rescue mission progressively
- moved up in the shuttle manifest until it was scheduled for only the
- second flight, but even that wasn't good enough in the end.
