If that flight is cancelled you've got basically no hope on BA. Only an 06:00 departure, not too delayed, from STN or LGW on Easyjet will get you to a Dutch airport in time to get to Eindhoven on the train by 10:30. If one of those flights is too delayed you're going to hate yourself for getting up at 04:00 to go to the airport.
You have to ask yourself, how important is that meeting?
