I will put a little of my thought on this "Pelosi-should-be-allowed-to-land-or-not" debacle.
Here are two possible scenarios:
1.
If the Chinese government does not intend on stopping Pelosi's plane from landing in Taipei, then things would be much simpler and less risky. Just refer to others who have talked about this in the previous posts in this thread.
In fact, if China wants to launch her reunification war on Taiwan in response to Pelosi's visit, by waiting until Pelosi's plane has left Taiwan, and that the US Navy's CSG and ESGs have lowered their war readiness somewhat would be more beneficial for China's cause. By then, the PLA would already have sufficient time to mobilize enough personnel and equipment.
Furthermore, the Pacific Typhoon Season is currently in full swing and will continue until late-October. Landing and combat operations cross-strait and around the island itself would be significantly affected in case any typhoon is heading towards Taiwan when the war is still in progress.
2.
If the Chinese government really intend on stopping Pelosi's plane from landing in Taipei, I believe that the PLA should make sure that Pelosi's plane can leave the Taiwan area and not come back - and
NOT shooting the her plane down.
Personally, I don't see how the pilots tasked with flying Pelosi's plane would dare to continue the flight to Taipei when fighters from the PLAAF and USAF + ROCAF are dueling at each other just around them. Remember what
@Patchwork_Chimera said - Pelosi's plane would high-tail out of the region in case any shooting starts.
Even if Pelosi is a daredevil, somehow (which she isn't - she has never been in the military in her entire life), the White House and especially the Pentagon would intervene on her behalf. Why? At least we have someone like General Milley who is clear-headed enough than many of those hawkish politicians in DC. That's also why the Pentagon said that Pelosi's visit is not a good idea in the first place.
As long as the PLA can cause some chaos around Taiwan when Pelosi is about to visit (such as engaging USAF and/or ROCAF fighter planes, conducting extra large scale military exercises right in the expected flight paths of her plane, firing Dong Feng missiles into waters near Taiwan, etc), then I believe the most striaghtforward protocol for the pilots onboard would be to fly Pelosi's plane towards Okinawa, Yokota or even Guam immediately. Remember that it is the responsibility and priority of the US military to make sure that Pelosi is safe and sound. Whether or not she can land in Taipei and meet English Vegetable is a different matter entirely.
Besides, I think that even if fighter planes from either or both sides got damaged and/or shot down, it would not lead to immediate escalation into a full-scale war, unless either side does the escalation first. If my intuition is correct based on the responses from the White House up till now, neither Beijing nor Washington DC wants to escalate this into a full-scale war. Phones in the Pentagon and/or the August 1st Building would ring like no tomorrow as soon as the confrontation begins, or in case the first shootings were reported.
