Many US airports have to move a lot of tin in little time. Consequently their multi-runway procedures are somewhat more adventurous than those we're accustomed to here in Europe. Of course safety should never be compromised, but if many of the current US procedures were to be changed, I would imagine that the resulting outcry from the public and politicians, as a consequence of the major delays that would ensue, would be heard this side of the ocean. What to do?
