This sounds a little bit like a short in the electrical system. Burning wires will definitely make your eyes burn because melting plastic is slightly toxic. That's just a guess, though.

There have been at least 10+ incidents of this type since the fall. Both here and abroad. I found it strange that it could possibly be an electrical problem, or unknown problem making crew and passengers ill....and yet they kept passengers on the plane for 4 hours!!

I just like to post the odd airline incidents. I don't want to miss anything.

a littl pepper spray will make your eyes burn , and make you 'choke up' even if you are across the room... probably not pepper spray though if there was smoke involved.

I think it's a good guess. Imagine being a passenger, sitting in a crowded plane with few exits, smelling smoke, and contemplating all the jet fuel in the wing and belly tanks, and the possibility of carbon monoxide dulling everyones senses while a hidden fire slowly grows under their feet.

And not being allowed to leave the plane.

Guess why I drive whenever possible...
