Though the pressure altitude is not consistent with the speed and vspeed evolution, speed and vspeed indicates the aircraft is already airborne and climbing at 182 kts (about 170 kts IAS). And one minute later it has gained 1000 ft and speed (250 kts). Then only the problems begin, may be after retracting the flaps.
The first thing I would normally do with FR24 data, after correcting for QNH, is to throw away transmitted VS values.
The aircraft climbed fairly steadily before levelling off at approximately 1050' AAL just over 60 seconds after rotation, so 2000+ fpm at any point seems a tad unlikely.
