I don't see anything inherently disrespectful about rasing the plane from the seabed. I recall people telling James Cameron that he should leave the Titanic alone but he made a great movie and brought the ship back in to the public imagination and didn't disrespect the fact many souls were lost tragically. The ship was deemed not economically viable to salvage but this plane is much much smaller and it may be worth putting in a museum.
I'm presuming you are offended on behalf of other people but if not can you elaborate why you find the idea so offensive or disrespectful?
