John Hancock Building standing tall. This building was designed by C. M Pei. It had a systemic flaw. In high winds a torsional effect was set up and many upper windows began to pop out.
Pei's reputation suffered greatly and the remedial cost was many $millions. The top level had to be set up with a wind counterbalance system. Image was recorded with a 4 x 5 in. view camera from in front of M.I.T.
