I've worked there, too, and yeah, the planes can suck... I was lucky, though. The show I did happened to coincide with some foggy weather, so there weren't as many planes as usual.
Actually, I was Hodel in the production of
Fiddler that
Elphaba mentioned!

(Hi,
Elphaba! So glad you liked the production!)
And
sdsm2006 is right, it shouldn't be a big issue with
Saigon, since it's almost a sung-through show. =)
