I landed at Birmingham today and along with most other passengers had to support myself on the seat in-front in order to avoid hitting it.
Seems like a good reason to ensure that seat belts are worn correctly.
Regarding 'wobbly' approaches, I have had many a 'cheek clenching' experience coming into NCL from the East (over the coast), but this always seems par for the course up here as we do tend to get our fair share of windy conditions.
Seat belts worn, expect a couple of 'wobbles' - no problem!
