Scud skimming
Yeah. The good old days. Take off on 27 ML. Into the cloud. Get the FE to open the cockpit door while accelerating to 350 Kts. (yeah - a REAL jet). Roll into the turn to SBG. Burst out of the flat cloud tops with 4000 FPM plus around 4000' into the brilliant rising sunlight with 30 degrees or so bank (Heh heh)!. Roll back to HDG and get FE to close the door. Sigh. Yeah.
