Cold war snacks
A highly reliable ex-aircrew member source (should such a thing be imaginable) spoke of a Lightning squadron challenge to achieve max altitude ere the chocolate marshmallow exploded. Said source - OK, my brother - was unable to recall any record. Can anyone out there comment, please? If you could, it'd amuse my dear brother, now 78 and gripped by Parkinson's Disease - a tragic irony for one who once lived (or died) by his speed and wits, I suspect. PMs welcome.
Thank you,
Ben Potter
