No problems with the 707s as such, just not making much money. They're kind of like the Pan Am of cargo, in days of olde they were the first cargo airline with a scheduled round-the-world service (starting and finishing at Beirut, of course), with stops in (can't remember exactly but) Basle, London, JFK
, Anchorage, Tokyo...not sure about the routing between Tokyo and Beirut, except the last stop before home was probably Dubai. They also flew 747s, receiving them - like MEA with THEIR 747s - literally on the eve of war in 1975. The war doomed both MEA and TMA, MEA were a major airline in the early 70s and Beirut was every bit as busy as Dubai is now - hard to imagine a civil war in such a developed, quasi-first world nation, but BEY went from having hundreds of departures a day (all 707s and 747s, nice) to a skeleton operation by MEA, with the 747s being used to fly to Cyprus and tanker back fuel for the 707s. That's pretty much how things were til 1990 (brave attempt to bring back the 747s with a route to JFK
83-85 being typical of a lull in the fighting that proved to be a false dawn). Nowadays, although peace has returned to Lebanon, business conditions are still sluggish in the absence of a more comprehensive peace settlement for the whole region eg Jerusalem.
I hope TMA can hold on and grow back to their former glory (same goes for MEA).
