I'm guessing one person? They'd also have to be boneheaded enough to hear instructions for the wrong aircraft, pull the parking break, run a few checklists and miss the 50k+ of metal sitting directly in front of them. I know it happens.... ALL THE TIME. You would be amazed how often. Personally I carry one of these http://www.hammacher.com/publish/734...cm_cat=1414665
Trust me, 5million candle power won't do the job. You'll need to spring for the 15. I know it's pitch black out there where lights should stand out but you're asking for trouble if you don't pack one of these in your bag. They work great, are portable, reliable, and I find the front legs are easy to put in between the chart holder and the window so it props itself up. All you do is taxi into place, kick on the ice lights, then hit the power button on this guy. With their eyelids melted they'll have no other option but to finally notice you. This puts an end to the already nonexistent threat of people not noticing you're on a runway when 50ft away, lights on, dark, in a shiny jet after having taxied behind you for the past 15min and two miles.
