So well said! I was a pilot on 747-400 for 8 years, and the Classic for 10 years before that. It is extremely difficult to spot people on the walkaround. After the walkaround, there is an extensive period of 30 minutes or more when access can be gained, and again during taxi, this is when a lot of stowaways make a break for it in the dark and climb aboard- times when they cannot be stopped. If these economic migrants are going to insist on doing this darn fool thing, it's impossible, apart from local security being beefed up, to stop them. They are not at the end of their tether to do this- they want a taste of the bright lights and wealth. No pilot should have any conscience about these idiots killing themselves like this.
