Concerning the www.nationair-canada.com:
1) Have you noticed that the author of this web site does not identify himself anywhere on his site. His name is Dale Humphrey, former frustrated flight attendant at Nationair and former SCAB at PWA.
2) Although some of the information on the website is true, most of it is a pack of lies.
3) Lastly, keep in mind that the mechanic who signed off the DC-8 that crashed in Jeddah boarded the aircraft himself. Believe me, he was no fool and would never have accepted to fly an aircraft that he would have believed unsafe.
Have a nice day!
