Too bad for your company that it's the left windshield, if it was the right windshield Bombardier has a procedure to just cover it in aluminum tape (a very specific aluminum tape and after some inspections) and ferry fly it back home to get the windshield replaced. I only know of this because I rolled into the hangar one day and there sat a Challenger with one of them taped over. Changing a windshield on a Challenger is challenging (see what I did there?), doing it overseas is going to just multiply the headache tenfold. We once had a G550 parked out somewhere in Hawaii and a taxiing G650 decided to assert its dominance by crashing its winglet into our winglet. You used to be able to get a disposition to fly a G-IV with one winglet removed but those days are gone. This quickly became a quagmire for everyone involved including Gulfstream, there's no hangars, ramp space is barely existent and everything required to repair both jets (including a team of technicians for each airplane) had to be shipped by air. The insurance companies weren't happy, the loan holders weren't happy, the charter companies weren't happy, the charter customers were very unhappy. But if you endeavor to persevere amazing things can be accomplished and eventually everything was repaired and ended up back where it was supposed to be. I hope you were headed home rather than abroad. I should also say that windshields on some of these "older" jets are getting very expensive and hard to buy. I'm not sure if the 605 group is experiencing the supply chain issues the 550 group is but Gulfstream won't even allow you to order a G-IV-G550 windshield unless it's shattered or you provide proof of troubleshooting on the heating elements and I think they cost about $100,000/per windshield, it seems as if the black and white definition regarding damage/wear/age are now grey and they'll decide if you need a new windshield.
