The worst bit of turbulence that i've experienced was back in May 2007 on a BA 744, whilst travelling from LHR to JFK
The flight had been uneventful until we starting flying over the tip of Canada. We experienced a couple of bumps here 'n there, but a few minutes later the turbulence was much stronger and your stomach "dropped" a couple of times. This carried on for a good 30/45 minutes.
Wasn't very scary for those who know that turbulence hardly bothers the aircraft (i.e me
). but there were a good few passengers in our cabin section that did not like what was going on what so ever.

The first time i've been properly scared about turbulence was in January 2007 when i was flying from FNC to LTN on a TOM 752.
As i hadn't been flying for ages, i developed a very minor "fear"
Before we tookoff, i was hoping that we wouldn't fly through any turbulence, and thankfully we did until we was on approach at Luton.
During this period, the turbulence was pretty rough and i just had visions of the aircraft plunging thousands of feet and into the ground below, obviusly i was being ridiculoud and we didn't!
