Etymologically, the entry records: From military contexts, where aircraft would fly low to avoid being detected by radar. Root origin matters for spelling because borrowed morphemes (Greek, Latin, Old French, Old English) carry their source-language orthographic conventions into modern English, which is why historical etymology is often the cleanest predictor of whether a cluster like "-ough", "-eau", or "-tion" will appear. For readers arriving here from a spelling check, the authoritative guidance is: the correct English form is slip under the radar, spelled S-L-I-P- -U-N-D-E-R- -T-H-E- -R-A-D-A-R, and any other sequence of those letters, regardless of how natural it feels, is a misspelling in standard orthography.
