I worry this will not be a “V” shaped recovery at all and it will take a protracted time for confidence to return to aviation. There is already a huge surplus of pilots and with more airlines set to go under this will only get worse. You’d fail the sanity part of the Class 1 medical if you think now is a good time to start training. Walk away, do something else for the next couple of years, don’t make a massive financial mistake which you will possibly never recover from.
