TTN, could be though I listed 17 which were crashes as opposed to one's like the runway fire at Scampton or the undercarriage collapse at Finningley. I considered these to be in a different category to the crash landing of XJ781 in Iran.
I omitted XH561 that damaged its undercarriage at Finingley as I did not know if that was an actual crash. There was one, I can't remember more details that did an unintentional wheels up landing. The aircraft went into ground effect and suffered hardly any damage.
There was another, XM600, we flew her to St Athan for the first Major at St Athan. On take-off on return her undercarriage door shut then the main wheel retracted with predictable consequences. As the aircraft landed at Cottesmore it was declared a Bomber Command accident rather than a Maintenance Command one.
