It's not that obvious. There is an inteview with F16 pilot who intercepted the 767 and he says the crew were specifically asking about the tail skid which, as previously mentioned, was indeed extended. I am not sure whether there is any alternative extension method for tail skid, but if there isn't - they must have switched the pumps on again(?).
