But that was relevant (sometimes). When Abeles and Murdoch were actively involved in doing RM some mischief, they sold his helo (VH-AND) out from underneath him so he couldn't commute to the city any longer. Cal found himself without a steed and ended up on the same B727 course as me whenever back in the day. (Or was it the B737 (?) too long ago to be sure .. one or the other).
