spoke to some crews re: airliners used as firefighters.
they recon they would only work somewhere flat like CA.
here in CO – hot and high airfields/large mountains – probably a no-go – even the Neptunes that have had their outboard jets taken off, sometimes have to downsize their loads, at times here.
I’ll post some pics of some lovely Neptunes on the Old Timers board in a few days, when I get home from Grand Junction, CO
