Otrex yes, I do confirm, Hellasjet caused havoc over the congested Gatwick airspace as they did not follow the climb restrictions on their sid. The point I was making was that after Gatwick director called them to let them know of the problem they had caused they were rude on the radio, and completely unaware of the sid climb restrictions. Mistakes can happen, ignorance is undesirable, but arrogance is dangerous especialy on the flight deck of a modern aircraft.
