No-one has posted yet.. seemingly simple diversion with no major incident so I guess it's a pretty quiet incident for Air Transat but still worth noting.

Quoting Canadian Press:
was diverted to St. John's because it had a cracked windshield.

Emergency crews were standing by.

The crack must have been pretty substantial for the crew to consider requesting emergency personal to be standing by or maybe I just don't know the magnitude of cracked glass. Would a small, hairline crack be considered a "mayday" and dispatching emergency crews or would the crack have to be pretty substantial.

Quoting Canadian Press:
Air Transat is also flying in a repair crew to fix the damaged jet.

Would they be flying with a new windshield or just repair the A310 in St. John's with available on-site materials? And where would they conduct this work in St. John's... Would they use a partner hanger or just do the maintenance on the apron (doesn't seem plausible)...

A replacement a/c flew into YYT with a new windscreen and MTC crews to fix the "broke" a/c. The replacement a/c will then take the pax to LGW.
There are'nt any hangers large enough to fit an A310 entirely. You could bring one nose in a few meters to do the fix. I did this with an Aer Lingus A332 a couple of years ago when it landed with a cracked windscreen.
I have however seen crews replace windscreens in the open as well.

In life, some days you are the bug..... some days you are the windshield!

Cracked windshields seem quite common. Just this year alone there have been about 60 reports of cracked windshields in the Canadian incident reports. There must be many hundreds worldwide. A few examples of the Canadian reports so far this year:

ACA695, an Air Canada Airbus A320, registration C-GIUE, was en route from St. John's (CYYT) to Toronto (CYYZ) when the crew declared a PAN situation due to a cracked left windshield. The crew requested and received a clearance to divert the flight to Halifax where the aircraft landed safely without further incident. The windshield was replaced and the aircraft has been returned to service.

At 10:09Z the aircraft reported a cracked windshield and requested descent to 34,000 ft. No emergency was declared. The aircraft received the requested clearance and reported level at 10:15Z.

The aircraft has been returned to service.
