This is no fly call that more should be informed on.
People have suffered due to congestion, blown out eardrums and possibly worse results are possible. I used to push myself when required by my previous employer to fly as a flight mechanic/maintenance rep. The last straw... I was cracking my jaw trying to clear my ears and found myself unable to equalize during descent, I staggered for several hours (equilibrium).
I made it to the bar to meet up with some friends I had planned on meeting and after about an hour (beer in hand) heard a squeel out of the pressurized ear and turned to my buddy and told him I just landed. After that I started rejecting flights if I was congested understanding the damage it can do.
This post was intended to be humorous and serious..
