L1011 for example.
Cracks develop enroute...no restrictions whatsoever
And on the Tristar windscreen change is easy. being prepared after a reported cracked windscreen in DXB, we replaced the windscreen on the 60min transit at BAH without a delay!, and the seal is rubber so no curing time involved.
The bolts are on the outside and are all the same length, all you need is a platform to stand on, and the crew can get on with their work in the flight deck.
To change a B737 screen is about 10 hours work, then dry the sealant, and wonder what the little bracket is for you have in your pocket.
