Transposition, Docking, Extraction And A Happy New Year

HERE'S TO WISHING EVERYONE A GREAT NEW YEAR!! Here are some images of Monograms 1/144 scale Saturn V top section with the Command module performing and extraction of the LM. This model of course is taken from the Saturn V model kit.

I real life the four open petals (doors) are supposed to fall away when opened allowing for a less chance of an accident.

From Wikipedia"
Transposition, docking, and extraction (abbreviated to TD&E, often just transposition and docking) is a space rendezvous maneuver performed during the Apollo lunar missions of the 1960s and 70s. It was performed after the trans lunar injection burn that placed the Apollo spacecraft on the trajectory towards the moon, but before reaching the Moon or attaining lunar orbit.
Transposition, docking and extraction was performed on all Apollo missions from Apollo 9 onward, as these flights carried the LM. The maneuver was first practiced on the earth-orbiting Apollo 7 flight, but the S-IVB utilized a LM fairing adapter that did not separate from the S-IVB, thus the crew could not approach the S-IVB in fear that the adapter "petals" would strike the Apollo CSM. This was corrected with all flights commencing with Apollo 8 when the fairing "petals" would fall away from the S-IVB.

The last mission to use the TD&E maneuver was the Apollo-Soyuz Test Project mission in which the Apollo CSM used the procedure to extract the docking adapter used to link up the Apollo and Soyuz 19 spacecraft in the first, and only joint mission between the U.S. and the Soviet Union (although there would be much future cooperation in space between the post-Soviet Roskosmos and NASA).

Nice. They fall off in real life, but it looks pretty good this way.
Happy New Year to you also Warren!
