Old Heathrow visit

[sp221156]

Just trying to put a date to a visit I made (as a young man!) to Heathrow back in 1971. Does any old-timer here have any record of KLM Boeing 747 PH-BUB visiting LHR in April/May of that year? Possibly it's first visit.

I would say it's a long shot - but there always seems to be someone, somewhere who knows.

Thanks

Steve
