RE rainbowair:
im in the local area at the moment and rainbow are still with their old reputation, i understand there have been changes with management etc but im told the feds are still keen on them, their aircraft are still all very old but its hard to say exactly what condition they are in,
LGB ATC get fustrated with them constantly... lots of go arounds/missed approaches largely as they have a massive uptake of students from the middle east and china, they send students solo who can barely string an english sentence together then ship them home by the bus load (literally!) when they are 'done' and in come another bus load of cadets, trust me there are some far better FTO's out there
over all... keep well away
