As logical as that sounds...it's wrong...he needs a visa even if not leaving the airport. The UK has a very snazzy website which tells you these things:If you don't leave the airport you shouldn't need a visa is what I thought, it's bull to need one for a stop over. It is not like you're actually leaving the airport.

You didn't need a visa because you were exempt. OP is not.I travelled through Heathrow in Feb to the USA. Spent almost 4 hours layover going and 9 hours coming back.
I did not need a UK visa.
