Most assuredly NOT a 'storm in a teacup'! A heavy landing is bad enough, but one which also causes a serious tailscrape will probably have very expensive repercussions involving extensive damage assessment and a specific repair modification programme.
Remember JAL123? After a tailscrape landing, a botched Boeing repair was carried out to the rear pressure bulkhead. When this ultimately failed in flight, 524 people in the B747 aircraft perished.
But WHY did this barely-controlled crash onto the IAD runway occur in the first place?
