There is a photograph of 419’s KB762/VR-J at dispersal in the book ‘Lancaster at War’ and I suspect that it may be an official Canadian photo although it is not credited as such ? In the background and under the wing of the Lanc is the church of St George which still stands today . Some details here ;

The church can be clearly seen on Google Earth and is also marked by a Panoramio icon so is easy to find . There is a small cluster of frying pan dispersals in that corner of the airfield and by comparing the photo to GE it is quite easy to make out which dispersal Jane is sat on . Of interest in this area are alpine flowers and maize , the seeds of which were collected in the Lancaster airframes whilst on Ops , brought back to the UK and washed from the airframe by rain to grow around the dispersals were they still thrive today . Adjacent to these dispersals is the bomb dump area and I have always thought it rather strange that the aircraft were parked so close to it ! I have some photos of those dispersals if they are of any use ?
NB ; Teesside Airport although officially now Durham Tees Valley Airport !
