Lol philidor..... So many MSNs this year and last year and every year were/are transported in separate convoys.......... MSN240 MSN241 MSN239 MSN238 MSN236 MSN197 etcetc just to name a phew.......
Ah ! That's not the same as carrying pieces from two MSNs on the same convoy ! Carrying some parts of one frame on one convoy and the rest on another one is rather common practice, while carrying parts from two frames on one convoy is rare - at least if we only consider the last five or six years, not the early days.
CV2016/17 1wing MSN197 1wing MSN236 and I must agree in fact, there was none back until CV2012/8 Wings MSN94 Tail MSN112.... But all first convoys in 2012 before CV2012/8 are composed MSNs..... Example CV2012/2 3 parts Fuselage MSN89MH WingsTail MSN110EK.
ALL convoys in 2011 had parts of different MSNs. In 2010 16 convoys out of 22 had parts of different MSNs, example CV2010/8 MSN69LH All parts except CenterFuselage + CenterFuselage MSN35KE1.
