The DC8, my first jet.
Yep you never forget your first jet - DC9 in my case. Bit
like the first time you fall in love isn't it - you never love
another woman quite the same way again.
And yep gear extension/extended was 300kt.
It was common practice to pull the gear/slats/flaps 10 kts
under placard. But design engineers in those days always
built in a fudge factor so us petrolheads never really took
things very sedately.
