Hex 053977 = octal 01234567 = made up code

[IanH]

053977 was E of Nottingham going N at 4000'

Not plotting but mlat on PP shows it.

PP and BS have it as a C-130 A97-003 but it was just below clouds looking and sounding like a Sea King.

No chance to get a scope on it.

looks like this is the octal equivalent of 01234567
