Flash Airlines was a private charter airline operating out of Cairo, Egypt that was part of the Flash Group tourism company. The airline operated two Boeing 737-3Q8 aircraft manufactured in 1993 on non-scheduled commercial passenger flights on both international and domestic routes.
The airline was established in 1995 as Heliopolis Airlines. It received its certificate of operation from the Egyptian authorities in 1996. It became a member of the Flash group in 2000. During that year Flash Airlines had one 737-300 with another that joined in 2002.
In 2002, Swiss aviation authorities performed a surprise inspection on SU-ZCF, a Flash Airlines Boeing 737-300. They discovered missing pilot oxygen masks, a lack of oxygen tanks, and inoperable cockpit instruments. The Swiss grounded the aircraft until Flash repaired the plane. Several days later, Switzerland banned Flash. Poland also banned Flash, while tour operators in Norway ceased contracting. In early 2004, SU-ZCF crashed while operating Flash's Flight 604. The subsequent investigation exposed poor safety measures and helped lead to the folding of Flash.
