A distant Mid Air Crossing with an "X" !

The weather and the clarity of atmosphere has been super clear since the last few weeks and so was the case tonight. I was imagining the moon when I caught two jets with contrails over the North Western horizon converging on each other and were about to cross. To my astonishment they actually crossed each other and later their contrails formed an X in the sky which was an unbelievable and an unusual sight. Later I found out that they actually crossed somewhere over Hafiziabad city around 72 kilometers away from my vantage point.
