The B-47 seems to have been a handful to take off and land, of 9 destroyed in the UK all but two were in close proximity to the runway. For example 1 May 55 at Fairford one crashed on take-off due to pilot error (all crew safe). The ASN page has an embeded 'U tube' video of a training film based on the incident from 2.10ish there is a short clip of the wing and no1 engine striking the runway
