I think I mentioned it before on pprune but about 18months after the Papa India crash I watched an Iraqi Trident start dropping from about 100ft after lifting off from RWY 10R at Heathrow. Pulled the wrong lever along with undercarriage retraction , I guess, and rectified just in time. The controller in the Tower noticed though, but only got a mumble from the pilot in response to 'Iraqixxx, are you OK?'
