I dunno, chairlifts used to get to me when I was skiing but the Midi doesn't for some reason. I'm far too engrossed in trying to spot the line up the Frendo and/or wondering at the sheer ambition of the engineering.
That said, somebody I met told me he was once on the upper Midi lift when they decided they needed to re-tension the support cables mid-journey. That involves lifting the hundred-ton concrete weights that provide the tension out of their shafts at Plan de l'Aiguille, changing where the cables are attached, and lowering them back down. Obviously, that means the gondola cars getting pretty cosy with the Frendo...
Also scary is the amount of drilling and tying that has to be done to stabilise the rock around the summit of the Midi. The joke goes that the Helbronner lift started out as a project to stop the Midi falling over (by tying it to the Gros Rognon), but I'm not sure it's very far from the truth.
