Did a fam flight with Dan Air to Stavanger in one of their (at the time) new 146s. The BAe test pilot who was in the left hand seat did a full power departure from Stavanger; full load of 85 pax (plus me in the jump seat) and over 2,000 ft by the upwind end.
On another fam flight (jump seat once again) out of Palma in a Britannia 767 also with a full pax load, brakes off to FL370 took just 20 min - I timed it!
