Re: 777?
Old yep
First ever flight was a 707 on Lufthansa as an unaccompanied minor ..
Sydney Singapore Bangkok New Delhi Athens Rome Frankfurt. Still remember the awful stench about an hour out of New Delhi, forced to disembark at Athens for 3 hours so the toilets could be fixed and cleaned, but the stew who assigned to look after me was stunning bit of German engineering
Home a year later same stops but a DC9 no issues
Also remember being on beach near RAAF Sale when they still flew Neptunes as maritime recon. The sqn flew right over us, mum grabbed the 2 of us from 5m away, has a shell scrape dug and was on top of us shaking like a leaf in the time between the first sound and them going over - mum was a 10yo in Hamburg during Gommorah
