You haven't heard a four engine bomber until you've heard a Lanc ;-) 4 Merlin's has a very unique sound, quite different from the 4 radial designs of Boeing and Consolidated. I always found that the US bombers sounded like airliners due to the use of radials. But I grew up in an area where there were still a few DC-6's and Convair's in service, so most of my early exposure to 4-radial designs were civilian types. -Adam -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
