43) Indeed: let X ∈ S(Yω , R1 ) and assume that d (Yω ,R1 ) (x) is attained at z ∈ (Yω , R1 ) and |z | ≥ ηq. Let also y˘ ∈ on the half-line from yω towards z. Let also y˜ ∈ be the point realizing d (x). 43). Furthermore, ˘ S(Yω , R1 ) ∩ {|x | ≥ Cq} is strictly above in the e N +1 -direction. ˘ and let z ∈ (Yω , R1 ) be realizing d To prove this, take x with |x | ≥ Cq by an elementary triangle similarity argument, |z | = r1 |x | r1 C˘ q ˘ ≥ ηq , ≥ const ≥ const Cq |x − yω | l+R if C˘ is large enough.

13) that x∗ − TY∗ ,R∗ x∗ ≤ const . 5), we get that ∇u(x∗ ) const TY∗ ,R∗ x∗ − x∗ + u(x∗ ) ≤ . 63) |∇u(x∗ )| R Flatness of Bernoulli jets 37 Also, since |TY∗ ,R∗ x∗ − y∗ | ≥ const R∗ , we have that ∇u(x∗ ) , eN |∇u(x∗ )| ≤ const q . 64), we have that ∇u(x∗ ) const · e N u(x∗ ) + |∇u(x∗ )| R const . t. 66) with c > 0 suitably small. 12), we ˘ also denote r˘ := r (Y˘ , R). 2) and Corollary 7), and let Y˘ denote the center of the cor˘ responding barrier: more explicitly, Y˘ = Y¯ − te N , for some t ∈ R and S(Y˘ , R) touches the graph of u from above for the first time coming from −∞ in the e N direction at some point X˘ .
