I hate the moment of having one foot on plane, one on bridge.
Jump with both feet.
Then you probably won't enjoy watching video footage of elevator failures.
I'm fine with that, but I rode in a boat a couple times, and the first step in/out from the pier was a doozy! Aircraft don't bob and float in the surf!
I still remember old trains where you could look down and see the track while stepping from one carriage to the next. Child me always thought it was cool.
Jump forward, either into the plane or into the bridge, or rest on the back foot? I think that either we train reflexes or our body will take a guess but who trains for that?
Ride either of them down, preferably the plane. Don’t fall out!
