Seems your rescue is on some databases, have checked the one I have access to and found the following for that date:
26-5-1971
RAF Lightning XS902/J of 5 Sqn. Crashed into the North Sea nine miles south east of Spurn Head,
15 miles north east of Grimsby, Yorkshire after the pilot ejected due to a reheat fire.
Pilot A. Macay.
If you want to add details of the helo you were in and supporting a/c and times etc I will happily add them to the record.
