WIZZ Air A320 detached from tug.....LTN
A WIZZ A320 looks to have detached from the tug during pushback this morning. Engine No2 intake has crashed into the tug

So how does an a/c being pushed BACKWARDS hit the tug when it becomes detatched? Normally when the pin breaks the a/c continues slowly backwards whilst you watch in amazement as the tug appears from under the nose wheel! Even if it was a push-pull the tug and the A320 should have been on the taxiway centreline, well away from the engines.
How intreaguing!

You obviously have very little knowledge of push-backs. About 90% of pusbacks are not in a straight line. When the pin breaks not only does the aircraft continue moving but the tug leaps forward due to the removal of the weight of the aircraft. During the tug drivers reaction time the tug can move a considerable distance. There are many, many well documented cases of subsequent collisions between tug and aircraft, some involving the tug driver in serious or fatal injury.

agreed with Shytehawk, at most airports it may seem the pushback is a straight line off the stand, but the A/C still needs to be turned to go the correct way down the taxi-way for the runway he/she will be using..
as for the tug leaping forward, to put it in simple terms.. imagine ur pulling a heavy weight on a rope, the rope breaks while your pulling it... u will go flying.. now imagine that reversed when it comes to pushing an aircraft which weighs upwards of 30 tons

Yes, obviously my 10 yrs of flying 737 or bigger and at least 5 shear pin breaks must provide me with no experience whatsoever about what happens normally during a pushback.
Of the 5 I've had, all on curved pushbacks NONE have led to the tug shooting towards the engine. Guess I've just been lucky.

Wzz A320 pushed back from stand 40 facing to the east. Tug and a/c jack-nifed (sp?). Tug at 90 degree angle to nosewheel, disconnected then because of the gradient (pushback goes slightly uphill) A320 rolled forward slightly into the tug.

Thanks for clearing that up. Obviously a lot more than a plain shear-pin snapping.
Shytehawk, if you'd bothered to read my post properly you would have seen that I said during a push-PULL the a/c and tug would have been in a straight line on the taxi centre-line. Also the initial poster had implied that the AIRCRAFT had hit the TUG and not vica-versa. That's why it sounded odd.
Main thing is that nobody was hurt.
