For many years Aviation had a growth rate of circa 6% per annum. Various events have sought to change that - events such as the financial meltdown in 2008, SARS, 9/11 and so on. After a hiatus, Aviation resumed its growth rate. I suggest this will happen again, after about 18 months when a decent/proper medicine will come out to give most of the human race immunity from this virus. So by 2003 we will be back to a new normal.
The main risks to this are the virus adapting to fight the vaccine, and the vaccine availability being held up by greedy Companies. But the Governments should prevent the latter.
The most scary thing, in my view, is the various Western Governments becoming addicted to their new found spending powers, and to the other powers that they are currently working up.
Meanwhile, they will take their eyes off China and Iran. That is what causes me to worry.
