I'm a structural engineer, so when I see forces I like to compare them to common forces I design for in buildings.
That engine produces 115,000 lb of thrust. If I take typical rebar, fy=60ksi, so I will need about 1.916in2, which is about 2 #9 bars.
Two engines per plane, so I could hold back the 777 at full power with 4 #9 rebars. Not bad!
