Delta planes involved in incident at Boston
 

On the news last night was images of another taxiing 'collision' between a Delta B767 and a Delta Connection CRJ at Boston-Logan airport.

The port wing/winglet of the 767 managed to dislodge the elevator of the CRJ which was at an intersection.

This is the second incident in recent weeks where a CRJ has been hit by a larger aircraft (AF A380 at JFK from memory).
