There are a number of folks that do look back and wish that they hadn't chosen to train to be a professional pilot since the September 11th attack 3 years ago. The important lesson to remember for these folks is that the airline industry is a "roller coaster". There will NEVER be long term stability in this industry, EVER (and there never has been). Just look to the oil crisis in the 1970s, the Gulf War in the early 1990s, the demise of PanAm and other legacy carriers, and the terrorist attacks 3 years ago. The airline industry represents an over-magnification of the general economy. There are very few airline captains retiring today that can say that they have never been furloughed or lost their job working for an airline due to it going out of business. It so important for folks getting into the industry to understand that even when hiring is awesome and there is no sign of downturn of the industry--IT WILL HAPPEN in due time. If you can accept this up front even when times are good, and love to fly (and EXPECT to be furloughed at some point), it can be a rewarding and satisfying career.
