Well there certainly was a rule banning single ignition aircraft flying through the Heathrow CTR but maybe it was dropped when it became Class D airspace.
When it was the equivalent of Class A years ago, we had an OC Flying at Farnborough who was (and I believe still is) a bigwig in the BGA; knowing my experience of gliding we often had little chats about it and he admitted to me one day he'd flown an RF4 through the Heathrow CTR on a Special VFR clearance 'even though he shouldn't as it only had single ignition'.
