Tiger1, 727 out of Southend

These won’t win any photographic competitions, but they may be of interest.
A friend rang to give the heads up that the 727 “Tiger1” was just about to take off from Southend.
So I managed to get these quick shots from my back garden. It headed North, did a trip around Norfolk, then headed
(I believe) to Lasham. I wonder if anyone has any more info ? I was told it may be about to be converted to an anti
pollution spray aircraft.
