The player most disturbed, I am sure, was Stuart Broad - whose father Chris was in one of the buses attacked and was lucky to survive.
Stuart told us that his father had called him at 2am to tell him he was OK. "He told me he had seen sights he wished he would never have to see." said the younger Broad. "It was all very blurred as the attack had only taken place an hour before when I spoke with him. But he told me his driver had been shot and killed and two other people in his vehicle had got shot. He sort of lay in cover while the carnage happened."
Hugh Morris, the England managing director, was also at the airport. There rarely seems a day that goes by on an England tour when we don't look to Morris to react to a major cricketing story, but this event was clearly deeply disturbing. "I'm shocked and stunned," he said. "It's an outrage we are all appalled at." He went on to tell us he'd been in contact with Sri Lanka's assistant coach, Englishmen Paul Farbrace, to see how he was after being injured in the attack, as well as offering sympathy to all those others effected by the incident.
England coach Andy Flower described the events in Lahore as "a sad day for Pakistan". He said: "There won't be cricket being played there for a very long time to come. Not just for cricketers but for any human beings this has been a shocking day."
The sombre mood around the England camp reflected concerns about fellow international cricketers, many of whom have become friends. We heard during the day that Andrew Flintoff, back in England, had immediately contacted his Lancashire team-mate Muttiah Muralitharan to see if he was OK.
But the mood also reflected the fact that players will in future not just have to worry about being caught up in potential terrorist incidents, but may well become the target of them.
Jonathan Agnew went straight onto Five Live Sport as we landed at Port of Spain having spent the flight speaking to players. He reflected that the landscape of Test cricket has changed. "The day has dawned that we hoped never would. We always hoped that cricketers would never be the targets but today they feel vulnerable," he said.
Chatting to players, officials and other media throughout the day we recalled that most of us have been in security cavalcades to grounds like the Gaddafi Stadium. Most of us recognised exactly where the attacks happened and we also knew many of those involved personally. We also recognised that although the incident was horrific, it could have been even worse.
We expected when we arrived in Port of Spain that most talk would be about whether England would pick Shah or Bopara, Ambrose or Prior or whether they'd play five bowlers or four on Friday.
But after what took place in Pakistan, such issues don't seem particularly important at the moment.
