Silly Season ...
Rest assured the no more than two overflights rule is still in full effect. Some points to consider. The majority of traffic around the Mach Loop is probably Hawk T2. The T2 systems including HUD are recorded to a solid state brick and are downloaded onto a server after every flight. Anyone can access anyone else's flight data and see EXACTLY what was going on. The Hawk T2 has RADALT and GPWS. The level of intolerance for any rule breaking is lower than it has ever been. The level of supervision is the highest it has ever been caused by various factors (not all positive). I can, however, state that I would be gobsmacked if anyone was proven to be doing anything illegal in the 'new' Hawk - why would you put your career on the line - and yes it would be taken that seriously!
The fun police moved in years ago - that's why I left ;-)
