2 aircraft clip wings at YYZ
 

If in doubt STOP and reassure yourself before continuing - no matter what ATC say or the follow-me says, it's YOUR responsibility.

Looks like the LOT was on 180 and the ROU inbound to 181:

Correct. ROU was coming in to 181; LOT was boarding at 180:

I love the (now deleted, but cached on Google) post on Facebook from Teamsters Canada (currently in dispute with Swissport):

Good to see Teamsters not letting the truth get in the way of a good story. :O

Some gates have an "A" centreline offset to the right to accommodate larger types. Maybe someone wasn't on the correct line.

OK, but if you have a wingwalker that doesn't know "he should have been watching the wing," that could be a problem.

Should probably be captioned "Union unconcerned about establishing the facts". :O

Interesting quote from the spokesman:

"There should have been wingwalkers on both of the aircraft". Really, on arriving flights ??

However he goes on to say that:

"The LOT aircraft may have been parked on the wrong line".
