(Feels strange to write Boeing when it was Douglas for so long)

Anyway, I flew out of LGB the other day and I was looking at the Boeing factory as I was waiting for my flight. 2 MD-11 in various stages of completion were stored outside (both in Lufthansa colors, one looked like a freighter and one looked like a passenger version. CL and CM, respecitvely, were the tail letters, or was it GL and GM - I couldn't see). Besides that, I could see a number of 717's (or MD-90's - the top of the tail looks the same to me) behind a low wall, only the tails stuck up behind the wall.

That leads me to two questions:

What A/C are still being made in LGB? Is it just MD-11 and B717, or is the C-17 still made there as well?

What contraption is used to support the MD-11 before the landing gear is mounted on the plane? One of the MD-11 could not have had landing gear, but is was stored outside on the tarmac. Looked strange since it was so high off the groud, but I could not see what it was resting on.

Anyone knows?
