In 1986 the boss of the company my then wife worked for chartered 2 Boeing 737s and flew the whole company to Sweden for a day trip , we landed at Volvo's private airport .
Coming back we were sat at the back of the plane , as we taxied onto the runway to the left there was about 50m of runway then a fence , to my surprise we turned so the plane was almost wheels in a field, I could see the fence behind us , I thought **** me does he need that 50m
There was no slow build up to speed, throttles at full power, the plane was shaking then a 3 word announcement
Immediate take off
He took his foot off the brake and it shot off down the runway
As we got airborne we flew over another fence which looked pretty close
I later found out the runway was right on the limit for a 737
