Rotate at the appropriate speed and you have to be something special (needs) not to get the Fin airborne on 2 engines, whether back in the 80s with Mk 101s or now in the 2010s with 103s. A clean fit GR1 wanted to fly (not to be mistaken with something like 1Ft14 fit at AAS or any where else in high density altitudes), and was as forgiving as a Hawk. As an ab-initio, all you had was an extra lever (for the sweep) to worry about, so getting it right wasn't rocket science. The cases discussed here are ones of extreme mishandling, and/or of the pilot being a 'Rip****', trying too hard to be clever. No other excuse.
