I'm not sure why Traveller ships would ever be "in orbit", they can just station keep at any particular point but that leads to the question of why not just land to rendezvous with the air/raft. If the ships were in orbit then the air/raft would have to accelerate to the ~8 km/sec orbital velocity to meet the ship and would then be in orbit itself anyway. 

It's difficult to shake the feeling that the traveller setting really doesn't understand any of this, a ship is either in space or on the surface of a planet despite the vague attempt at vector movement rules at one point.

 Note that says that it can 'reach orbit' but not necessarily 'enter an orbital path'. That quote isn't solid proof they could orbit, but they can get to the height of an orbit to rendezvous. Now, maybe they can orbit... but that quote doesn't say that.

CT Book 3, page 23 says:  An air/raft can reach orbit in several hours (number of hours equal to planetary size digit in the UPP); passengers must wear vacc suits and
interplanetary travel in an air/raft is not possible.

Which might have resulted from a misunderstanding of what "orbit" is. The car can lift itself to orbital distance but not attain orbital velocity and just fall back down again.

Yeah, that's what it said!

As I recall. it took a number of hours to get into 'space' but the basic idea was that the craft would start rising & just keep going up & up & up.

I remember thinking how weird it would be to see something like that.

Which is ... insane. You can take your family car to orbit?

I guess the Tesla Roadster SpaceX edition isn't that far off.

It's also been an explicit part of the OTU for a long, long time.
Air/rafts have always used it, and they date from the original LBBs.

Yep, and there's even an explicit description of how to use an air/raft to get into orbit in one of the early pubs.
All that's needed extra is a vaccsuit!
