when I was a teenager I was an air cadet... flew on aN 11 hour AEW flight onboard a shackleton ...basicallya descendant of the Lancaster, a 10 hour fishery protection flight on a Nimrod and went solo 1 day after my 16th birthday in an old kirby cadet wooden glider, still glide now and again. the take off in a fully fuelled Shack WAS SOMETHING ELSE , the gap between take off velocity V1 stick back and v2 safe airspeed no stall V2 was muuuuchhh loonger than I would have wished, could almost hear a collective sigh of relief from the crew over the headset LOL.
